    The institutionalization of clinical research in Argentina reached its point of greatest maturity with the creation, in 1957, of the Institute of Medical Investigations (Instituto de Investigaciones Médicas) of the Faculty of Medicine of the Universidad de Buenos Aires, and the drive of the man who was its director for almost 20 years, Alfredo Lanari. In this paper I analyze the ways in which he generated a style of clinical research and a referential position in local medical field that allowed him to carry out said institutional realization. This achievement was the result of a personal enterprise and at the same time part of a larger context of transformations within the medical discipline world-wide and at the Universidad de Buenos Aires. This study was carried out combining oral and documentary sources, such as interviews with physicians at the Institute of Medical Investigations, members of the journal Medicina and of the Argentine Society of Clinical Investigation (Sociedad Argentina de Investigación Clínica), as well as academic files and scientific articles.

    During the preparation of an exhibition in Pavia dedicated to the centennial anniversary of the death of the Italian Pathologist Paolo Mantegazza, a strange cheratinic horn was found at the Museum for the History of the University of Pavia labelled as 'spur of a cock transplanted into an ear of a cow.' After some historical investigation, we found this strange object was at the centre of a scientific correspondence between Mantegazza and Charles Darwin, who made reference to it in his book The Variation of Animals and Plants under Domestication.

    The type specimens of amphibians and reptiles of the Museo de Historia Natural Alfredo Dugès, at the University of Guanajuato (MADUG) were reviewed following Smith & Necker's (1943) summary. Owing to this collection's eventful history and its historical importance as the oldest herpetological collection in Mexico, a review of its conservation status was needed. After many years, the collection has received proper recognition at the University of Guanajuato with a portion of the herpetological types considered "Precious Assets" of the university. We found 34 type specimens pertaining to 18 taxa; six are additional specimens to those previously reported; six herpetological types are missing, including the body of the type of Adelophis copei. All specimens are in good to reasonable condition except for the type of Rhinocheilus antonii, which has dried out completely. All specimens are illustrated to show their condition.

    Dr. Cora Mayers Glehy, was the director of the Nursing School, head of the Department of Health Education of the General Health Office, a founding member of the Pediatric Society and Dr. Alfredo Demaría Andreani, was a prominent student leader, first sanitarian graduated in the University of John Hopkins, director of Health, professor of the Chair of Hygiene and Preventive Medicine. Both were brilliant academics of the Faculty of Medicine of the University of Chile in the early 1930's and great achievements were expected from them by the medical and university community. These hopes and longings were destroyed when they tragically ended their lives on the morning of a Monday, January 12, 1931.

    The work provides the analysis of the nursing reports written by the nursing staff on duty at the asylum "Paolo Pini" from 1944 to 1947. description of the nursing report evolution, analyses of the quantitative and qualitative matters. Study of the evolution of the records: enhancement of the description of the patient, integration between medical and nursing assistance, assumption of responsi- bility (for instance through the signature). A sampling of 355 medical records has been analysed. The nursing records have been identified according to the theoretical model of Marisa Cantarelli. They have been compared with the current standard reported in literature. If recognizable signatures were present, they have been checked in the archives of the Province of Milan. 219 records concerning nursing assistance have been selected. The record changed during the years assuming a definite structure, and became a pre printed form; its use spread in all the wards of the hospital. The record deals with nursing assistance needs, and improves during the years becoming more and more detailed and regular. During the analysed time frame, the nursing reports at "Paolo Pini" improve and become more exhaustive and regular; they prove to be part of the medical record, showing a good integration between doctors and nurses activities. The evolution of this tool confirms the need of highlighting and improving the assistance practice.

    Wasson, John T.; DePaolo, Donald J.

    We honor Don DePaolo with the Macelwane Award for several key contributions to the earth sciences. While a graduate student at Caltech Don recognized that the study of an isotopic parent—daughter pair having the same volatility and the same host phases could eliminate many of the ambiguities that had plagued previous attempts to apply isotopic data to the study of mantle reservoirs and that the 147Sm-143Nd system was such a geochemically coherent pair.Following Gunter Lugmair's pioneering work on meteorites, Don was one of the first to work out laboratory techniques for the study of Sm and Nd; these techniques and the high-precision mass spectrometers of the Wasserburg lab allowed Don and Jerry to demonstrate in several key papers that there were at least two major mantle reservoirs and to examine earth structural models that could account for the observations. Don continues to contribute new ideas to this area; for example, in a paper in press he discusses the use of 176Lu-176Hf results to place constraints on the rate of crustal recycling.

    In Mexico, maternal mortality has fallen substantially in recent decades. Although according to the Secretaria de Salud, in Tamaulipas the maternal mortality rate has increased in recent years. Despite these facts, Tamaulipas ranks among the ten institutions with the lowest level of maternal mortality. To describe the basic elements of epidemiologic behavior of maternal mortality during a period of ten years at the Gynecology and Obstetrics department of the Hospital General de Matamoros Dr. Alfredo Pumarejo Lafaurie in Tamaulipas, Mexico. A descriptive, transverse, retrospective and a cases series research was carried out at the Gynecology and Obstetrics department of the Hospital General de Matamoros Dr. Alfredo Pumarejo Lafaurie in Tamaulipas, Mexico. There was a revision of the expedients of direct and indirect obstetric maternal deaths occurred from January 1, 1998 to December 31, 2007. We used descriptive statistics with central trend measurements and standard deviation. 30 obstetric maternal deaths were registered. Maternal death ratio was 87.2 x 100,000 live births during the 10 years. The average age of patients was 25.1 +/- 7.8 years old. 54% were in their first pregnancy. Only 20% had adequate prenatal control. Direct obstetric causes were 60% and indirect obstetric causes 40%. The main causes of maternal deaths were preeclampsia/eclampsia (27%), obstetric hemorrhage (20%) and gravid-puerperal sepsis (13%). 83% was foreseeable. It was noted a clear trend towards the reduction in the maternal mortality ratio in the decade from 1998 to 2007. Preeclampsia-eclampsia and obstetric hemorrhage remain the main causes of maternal death. The maternal mortality ratio tended to invest when comparing the first five years with the last five years of the study, which talks about improvements in management and direct obstetric causes prevention.

  13. Paolo Sarpi and the first Copernican tidal theory.

    PubMed

    Naylor, Ron

    2014-12-01

    Despite his demanding religious responsibilities, Paolo Sarpi maintained an active involvement in science between 1578 and 1598- as his Pensieri reveal. They show that from 1585 onwards he studied the Copernican theory and recorded arguments in its favour. The fact that for 1595 they include an outline of a Copernican tidal theory resembling Galileo's Dialogue theory is well known. But examined closely, Sarpi's theory is found to be different from that of the Dialogue in several important respects. That Sarpi was a Copernican by 1592 is revealed by other of his pensieri, whereas at that time we know that Galileo was not. The examination of Sarpi's tidal theory and of the work of Galileo in this period indicates that the theory Sarpi recorded in 1595 was of his own creation. The appreciation that the theory was Sarpi's and that Galileo subsequently came to change his views on the Copernican theory and adopted the tidal theory has major implications for our understanding of the significance of Sarpi's contribution to the Scientific Revolution. Moreover, it appears that several of the most significant theoretical features of the tidal theory published by Galileo in the Dialogue - and which proved of lasting value - were in reality Sarpi's.

  14. Ethical perspectives and ramifications of the Paolo Macchiarini case.

    2017-01-01

    The Paolo Macchiarini case has several ethical ramifications. Professor Macchiarini, formerly of the Karolinska Institutet (KI), became famous for the tracheal surgeries he conducted between 2008 and 2014. His rapid rise to fame was followed by an almost equally rapid fall from grace as official reports, articles in newspapers and television programmes revealed several aspects related to misconduct in his curriculum vitae, professional practices and publishing-related activity. Formal misconduct reports issued by four KI co-workers in late 2014, then again in 2016, coupled with social scandals, including the tricking of a famous US television newscaster into a false marriage, a previous arrest in Italy for apparent bribery, and acute narcissism, all tainted Macchiarini's legend. In the short space of just two years, Macchiarini was no longer remembered for the revolutionary changes he had claimed to have brought about in stem cell research and regenerative medicine. Instead, at least seven dead patients later, Macchiarini faces potential aggravated manslaughter charges and an uphill battle to save his published research, now shrouded in scandal and scientific doubt, from being retracted and scratched out from the list of verified medical science. This paper examines some of the possible ethical ramifications of the Macchiarini case.

    Urology, having been part of general surgery for centuries, was completely consolidated as a medical speciality in the middle of the XX Century as the result of years of evolution and development, and all the studies and works of certain authors that represent today the mainstays of our speciality. Valencia in the middle of the 20th century saw the birth of new hospitals including the "Ciudad Sanitaria La Fe". Alfredo Tramoyeres Cases was the first chairman of the Department of Urology. This article reviews his long and fertile professional life. We have reviewed all his scientific works. The articles have been obtained from Medicina Española, Revista Española de Cirugía Traumatológica y Ortopedia, and Archivos Españoles de Urología. His most important urological work is his doctoral thesis with the title "Sigmoid-procto-ureterostomy: personal modification" published in Valencia in 1976. For his biography we used the" Biographic and bibliographic history of the Spanish Urology over the XX century" and interviews with family members. We emphasize his thorough description of the various types of urinary diversion. He covers the topics of bladder diverticula and bladder neck disorders, in which he supports surgical treatment. Finally, he sets out the rupture of the posterior urethra and various treatments for prostate cancer at that time. Alfredo Tramoyeres Cases contributed to the definitive consolidation of our speciality in the area of Valencia during the second half of the XX century, through his long professional life, with his interesting scientific contributions.

  16. Chromosomenindividualität or Entmischung? The debate between Paolo Della Valle and Edmund B. Wilson.

    PubMed

    Volpone, Alessandro

    2015-01-01

    At the beginning of the twentieth century, the Italian cytologist Paolo Della Valle developed a theory of instable chromosomes (teoria dei cromosomi labili). He radically criticized the so-called Sutton-Boveri hypothesis (Martins and Martins, Genetics and Molecular Biology, 22:261-271, 1999), focusing on numerical constancy in the species and individuality. On the basis of bibliographical review and personal observations, he maintained that the chromosomes were neither stable bodies, nor permanent structures, but transitory cellular materials, resulting from the periodical rearrangement of the chromatin during the cell division. German and English-speaking biologists reacted. The paper shows some content of the argumentations used by Thomas H. Montgomery and especially Edmund B. Wilson. The discussion was characterized by the same data which is interpretedby different scholars in different ways. And the point is that no one of them had the decisive test to demonstrate his own point of view. Wilson simply invoked on his behalf a certain 'common sense', defending at least a 'high degree of constancy'. The debate waned along with the reception of Morgan's chromosome theory of heredity, but only the advent of molecular biology definitively stated the nature of chromosomes as permanent structures of the cell.

    The National Cancer Institute of Bari (Istituto di Ricovero e Cura a Carattere Scientifico, IRCCS) has been involved since the conception of the project of the Italian Ministry for Health aimed to validate the applicability of the Organisation of European Cancer Institutes (OECI) accreditation and designation (A&D) model to the Network of Italian Cancer Centers, IRCCS, of Alleanza Contro il Cancro. The self-assessment phase of the Institute started in September 2013 and ended in June 2014. All documents and tools were transferred to the OECI A&D Board in June 2014 and a 2-day peer review visit was conducted in October 2014 by an international qualified audit team. The Institute received its final designation and certification in June 2015. The OECI A&D Board, in its final report, came to the conclusion that Istituto Tumori "Giovanni Paolo II" of Bari has a strong research component with some essential elements of comprehensive cancer care still under development; the lack of a system for using outcome data for the strategic management approach to decision-making and missing a regular internal audit system eventually helping further quality improvement were reported as examples of areas with opportunities for improvement. The OECI A&D process represented a great opportunity for the cancer center to benchmark the quality of its performance according to standard parameters in comparison with other international centers and to further develop a participatory group identity. The common goal of accreditation was real and participatory with long-lasting positive effects. We agree with the OECI comments about the next areas of work in which the Institute could produce future further efforts: the use of its powerful IT system as a means for outcome analysis and empowerment projects for its cancer patients.

    Benecke, Mark; Rodriguez y Rowinski, Miguel

    2002-01-01

    This is the first scientific report on the crimes of the homosexual paedophile sadist Luis Alfredo Garavito Cubillos, based on a research stay of the authors in Columbia, and including discussions with the investigators, and the offender. Between 1992 and 1999, Garavito killed more than 200 children in the core age span between 8 and 13 years (as an exception, 6 to 16 years). His modus operandi remained stable. During daytime, he lured children of a lower social status out of crowded parts of the city into hidden areas that were overgrown with high plants. Garavito promised either payment for easy work, or drugs, or made other socially believable offers. The children were tied up, tortured, raped, and killed by at least one cut in the lateral part of the neck, or by decapitation. During the killings, Garavito was drunk. Even after his arrest (for attempted sexual abuse under a wrong identity) it was not immediately possible to track his crimes since Garavito had frequently changed his places of stay and his jobs. He also grew different hairdos and used wrong names. During his still ongoing confessions, he directs the investigators correctly to all scenes of crime spread over large parts of Columbia. In our report, we give an overview over the course of investigations, hint to similarities in the cases of the German serial killer Denke (1920's) and homosexual paedophile serial killer Jürgen Bartsch (1960's), and give preliminary impressions on the offender's personality. Furthermore, the violent environment and juridical peculiarities in Columbia are discussed. In spite of a total penalty of 2600 years in prison, it is formally well possible that Garavito will be released out of prison within the next 10 to 20 years, i.e. even before the maximum sentence of 40 years will be over.

  19. [The ideas that are seen. Form and perception in Goethe and Paolo Bozzi].

    PubMed

    Giacomoni, Paola

    2013-01-01

    This article presents a comparative analysis of Paolo Bozzi's experimental phenomenology and of J.W. Goethe's morphological method, which is considered one of the Italian scholar's sources of inspiration. Starting from Bozzi's education within the Gestalt psychology tradition, under the guidance of Gaetano Kanizsa, and taking into account also the recent interest shown for Bozzi by several exponents of the analytic tradition, this work draws attention to the basic features of the methodology adopted by the perceptologist in his work. In this regard, what proves to be fundamental is the role played by the various techniques of inter-observation by means of an active and practical approach to the material, rather than a purely contemplative one. Bozzi's interest in Goethe's naturalistic writings, from the morphological ones to the Farbenlehre (Theory of colours), makes it possible to highlight significant analogies and conceptual continuities with Goethe's epistemology. First of all, a link between these two styles of research is provided by the subject "form," or Gestalt, and its direct, accurate observation, as well as its presence in non-conventional contexts and its non-metaphysical character. Furthermore, it is evident that both authors employ a conception of experiment that is repeatable, conducted almost always in conditions that are open and not of the laboratory. Not less relevant is their scientific style, in which the distinction between the context of discovery and the context of justification plays no role. At the same time the extraordinary communication skills of both authors play a crucial role: their non-academic way of writing accompanied by a sense of rigour and correctness makes the results outstanding and unique.

  20. Should the definition of "sleep hygiene" be antedated of a century? A historical note based on an old book by Paolo Mantegazza, rediscovered. To place in a new historical context the development of the concept of sleep hygiene.

    2013-05-01

    The article contains a historical note on the concept of sleep hygiene, developed in 1977 by Peter Hauri, who developed a set of sleep-promoting rules, considered the fundament for sleep-hygiene techniques. Somnologists, unanimously ascribed to Hauri the fatherhood of the lucky term, while numerous books included at least a section on sleep hygiene. "Inadequate sleep hygiene" was included as a nosological entity in the International Classification of Sleep Disorders. This article intends to demonstrate that the concept of sleep hygiene was developed many years before, thanks to the pioneering work of Paolo Mantegazza, a scientist and a professor in the Medical School of the University of Pavia, Italy. After presenting briefly the history of the University of Pavia and illustrating the profile of Paolo Mantegazza, the article presents the original book published by Mantegazza in 1864 (second edition in 1865). The authors report extensive citations of Mantegazza's original book dealing with sleep hygiene. Mantegazza's indications, compared with Hauri's rules show important similarities. The authors support the view that the fatherhood of sleep hygiene should be acknowledged to Mantegazza and antedated to 1864. Hauri keeps the merit of giving more solid scientific roots to the concept of sleep hygiene and of inserting it in the frame of modern sleep medicine.

    "Efficient Solutions and Cost-Optimal Analysis for Existing School Buildings" (Paolo Maria Congedo, Delia D'Agostino, Cristina Baglivo, Giuliano Tornese, Ilaria Zacà) [1] is the paper that refers to this article. It reports the data related to the establishment of several variants of energy efficient retrofit measures selected for two existing school buildings located in the Mediterranean area. In compliance with the cost-optimal analysis described in the Energy Performance of Buildings Directive and its guidelines (EU, Directive, EU 244,) [2], [3], these data are useful for the integration of renewable energy sources and high performance technical systems for school renovation. The data of cost-efficient high performance solutions are provided in tables that are explained within the following sections. The data focus on the describe school refurbishment sector to which European policies and investments are directed. A methodological approach already used in previous studies about new buildings is followed (Baglivo Cristina, Congedo Paolo Maria, D׳Agostino Delia, Zacà Ilaria, 2015; IlariaZacà, Delia D'Agostino, Paolo Maria Congedo, Cristina Baglivo; Baglivo Cristina, Congedo Paolo Maria, D'Agostino Delia, Zacà Ilaria, 2015; Ilaria Zacà, Delia D'Agostino, Paolo Maria Congedo, Cristina Baglivo, 2015; Paolo Maria Congedo, Cristina Baglivo, IlariaZacà, Delia D'Agostino,2015) [4], [5], [6], [7], [8].

    2012-09-01

    The first great Thai ruler to encourage the adoption of Western culture and technology was King Narai, and his enlightened attitude led to the rapid development of Thailand. King Narai also had a passion for astronomy, and he pursued this interest by allowing French Jesuit missionaries to set up a large modern well-equipped astronomical observatory in Lopburi Province between AD 1685 and 1687. This was known as the Wat San Paolo Observatory, and King Narai and the missionaries observed a total lunar eclipse on 10 December 1685 and a partial solar eclipse on 30 April 1688. These observations and others made at Wat San Paolo Observatory during the 1680s marked the start of modern scientific astronomy in Thailand. In this paper we discuss King Narai's scientific and other interests, the founding of the Wat San Paolo Observatory, the missionaries who conducted the astronomical programs, their instruments and their observations. We also describe the surviving ruins of the Observatory and their interpretation as a site of national scientific importance in Thailand.

The community, Buckeye Road, questions notions of U.S. American identity as middle-class, WASP, and heterosexual. Buckeye can easily be viewed as a romanticized utopia that offers an alternative to consumer capitalism, urban sprawl, the…

    Specific Learning Disorders (SLD) therefore represent chronic, not temporary disorders with varying degrees of expression throughout life. The beginning of imaging, anatomy and genetics studies have made it possible to investigate the brain organization of individuals suffering from SLD (Deheane, 2009). The purpose of this paper is to describe a treatment method for reading and writing disorders through an intervention based on the integration of a sublexical method and a neuropsychological approach, with assistive technologies in the study of a single case. The protocol is based on the modularization theory (Karmiloff-Smith, 1990). The data presented in this paper with a A-B-A basic experimental drawing. This study confirms the degree of effectiveness of the treatments based on the automated identification of syllables and words together with the integrated enhancement of neuropsychological aspects such as visual attention and phonological loop (Benso, 2008), although in the follow-up condition only some abilities maintain the progress achieved. As previously mentioned, the SLD represents a chronic disorder, consequently the treatment does not solve the root cause of the problem, but can grant a use of the process decidedly more instrumental to everyday life.

    2015-03-01

    The Catastrophic Disruption (CD) Workshops have become a tradition for the various communities interested in collisional processes. The first one was organized in 1985 by the missed Prof. Paolo Farinella from the University of Pisa and his colleague Paolo Paolicchi, who understood the fundamental importance of collisional processes in the history of the Solar System. It was followed by subsequent workshops in Belgrade (Serbia, 1987), Kyoto (Japan, 1990), Gubbio (Italy, 1993), the Timberline Lodge (Oregon, USA, 1998), Cannes (France, 2003) and Alicante (Spain, 2007). The CD workshops are typically separated by 3-6 years, accounting for the required amount of time to perform subsequent advances in the field motivating the interest of the relevant scientific community for getting together to discuss new results and evolving directions in the field.

    The IX Mexican Workshop on Particles and Fields was held in the beautiful city of Colima, in the South-West of Mexico, from 17-22 November 2003. The proceedings of the Workshop were delayed due to problems with a previous publisher, we are very grateful that Journal of Physics: Conference Series kindly agreed to publish the proceedings rapidly at this late stage. The Workshop aimed to cover, through invited lectures delivered by internationally known experts, the most recent developments in the field. There was also a series of short seminars as well as a poster session, which allowed the whole community to participate with their most recent research results. A special session was dedicated to awarding the Division Medal to Professor Benjamin Grinstein, from The University of California, San Diego, for his outstanding contributions to the field. This volume contains the written version of the material presented at the Workshop. The Workshop was attended by more than 100 participants, including faculty members, postdocs and graduate students. It was organized by the Particles and Fields Division of the Mexican Physical Society, and generously sponsored by several institutions: Universidad de Colima, Universidad Nacional Autónoma de México, Universidad Michoacana de San Nicolás Hidalgo, Centro de Investigaciones y Estudios Avanzados del IPN (CINVESTAV), Consejo Nacional de Ciencia y Tecnología (Conacyt). The Local Organizing Committee was integrated by Paolo Amore, Alfredo Aranda, Carlos Moisés Hernóndez Suórez (Director of the Physics Faculty), Arturo Gonzólez Larios, Enrique Farías Martínez, and Myriam Cruz Calvario, all from the University of Colima. The members of the National Organizing Committee were Adnan Bashir (IFM-UMSHN), Jens Erler (IF-UNAM), Heriberto Castilla Valdés (CINVESTAV-U.Zacatenco), Gabriel López Castro (CINVESTAV-U.Zacatenco), Myriam Mondragón (IF-UNAM) and Luis Villaseñ or (IFM-UMSHN).

    For many years a good introductory book for undergraduate and postgraduate students on remote sensing of the Earth's land surface, which was not starting with an emphasis on traditional photographic techniques, was missing. In 2010 the first edition of the book Fundamentals of Satellite Remote Sensing by Emilio Chuvieco and Alfredo Huete was published by CRC Press and it was filling this gap. Now the second edition by Emilio Chuvieco was published by CRC Press. This second edition is made more attractive by the use of colour and including colour illustrations instead of the black-and-white ones in the first edition.

    The paper presents the results of a case study conducted on the Holocene alluvial deposits of the Tiber River valley, in the city of Rome. The main test site selected for the study, Valco S. Paolo, is located about 2 km South of Rome's historical centre. The alluvial deposits were dynamically characterized in a comprehensive way via site investigations and geotechnical laboratory tests. Normalized shear modulus decay and damping curves (G/G0 and D/D0 vs γ) were obtained for the dominantly fine-grained levels. The curves demonstrate that these levels have a more marked shear stiffness decay if compared with the underlying Pliocene bedrock. Decay curves from laboratory tests for the Tiber alluvia correlated well with the trend of the function proposed by Hardin and Drnevich, making it possible to derive their specific interpolation function coefficients. Use was made of the extrapolation of the findings from the Valco S. Paolo test site to a large part of Rome's historical centre by means of two other test sites, supported by an engineering-geology model of the complex spatial distribution of the Tiber alluvia. The experimental Valco S. Paolo Vs profile was extrapolated to the other test sites on the basis of a stratigraphic criterion; the analysis of seismic noise measurements, obtained for the three test sites, validated the engineering-geology based extrapolation and showed that the main rigidity contrast occurs inside the alluvial body (at the contact with the underlying basal gravel-level G) and not between the alluvia and the Plio-Pleistocene bedrock, composed of highly consistent clay (Marne Vaticane). The 1D modeling of local seismic response to the maximum expected earthquakes in the city of Rome confirms that the deposits have one principal mode of vibration at about 1 Hz. However, the simulation also evidenced that the silty-clay deposits (level C), making up the most part of the Tiber alluvial body, play a key role in characterizing the soil column

  18. The tropics, science, and leishmaniasis: an analysis of the circulation of knowledge and asymmetries.

    PubMed

    Jogas, Denis Guedes

    2017-01-01

    The article investigates the process of circulation of knowledge which occurred during the first decades of the twentieth century between the South American researchers Edmundo Escomel (Peru) and Alfredo Da Matta (Brazil) and the Europeans Alphonse Laveran (France) and Patrick Manson (England) with regard to the definition and validation of espundia as a disease specific to South America, while simultaneously the need to insert this illness into the newly created group of diseases called the "leishmaniasis" was proposed. Sharing recent concerns in considering historical research beyond the limits imposed by the Nation-state as a category that organizes narratives, it dialogs with some apologists of global and transnational history, situating this specific case within this analytical perspective.

    In humans, insulin sensitivity varies according to time of day, with decreased values in the evening and at night. Mechanisms responsible for the diurnal variation in insulin sensitivity are unclear. We investigated whether human adipose tissue (AT) expresses intrinsic circadian rhythms in insulin sensitivity that could contribute to this phenomenon. Subcutaneous and visceral AT biopsies were obtained from extremely obese participants (body mass index, 41.8 ± 6.3 kg/m(2); 46 ± 11 y) during gastric-bypass surgery. To assess the rhythm in insulin signaling, AKT phosphorylation was determined every 4 h over 24 h in vitro in response to different insulin concentrations (0, 1, 10, and 100 nM). Data revealed that subcutaneous AT exhibited robust circadian rhythms in insulin signaling (P < 0.00001). Insulin sensitivity reached its maximum (acrophase) around noon, being 54% higher than during midnight (P = 0.009). The amplitude of the rhythm was positively correlated with in vivo sleep duration (r = 0.53; P = 0.023) and negatively correlated with in vivo bedtime (r = -0.54; P = 0.020). No circadian rhythms were detected in visceral AT (P = 0.643). Here, we demonstrate the relevance of the time of the day for how sensitive AT is to the effects of insulin. Subcutaneous AT shows an endogenous circadian rhythm in insulin sensitivity that could provide an underlying mechanism for the daily rhythm in systemic insulin sensitivity.-Carrasco-Benso, M.

  4. A Spectral Study of a New Class of Radio Quasars

    2003-01-01

    This document serves as a final technical report for NASA grants NAG5-9995 and NAG5-9533, entitled 'A Spectral Study of a New Class of Radio Quasars.' The purpose of these grants were to support observations made using the BeppoSAX satellite. The observations took place over two years and covered two SAX observing cycles, respectively AO-3 and AO-4. During this time, I was employed both at Johns Hopkins University (NAG5-9995) and the University of Maryland, Baltimore County (NAG5-9533). As the research on these grants was on the same subject and my employment at JHU and UMBC has been consecutive, this document therefore covers both grants. The targets for these observations were four radio-loud quasars chosen from the first two X-ray selected samples of such objects. These were the brightest examples of the newly found class of X-ray loud flat-spectrum radio quasars, which prior to 1997, had never been seen before. However, my previous work with collaborators Paolo Padovani and Paolo Giommi on the DXRBS survey showed that they make up about 25% of the population of flat-spectrum radio quasars, but had not been seen before because of selection biases (all previous samples of these objects had been compiled in the radio). The purpose of the SAX observations was to investigate the shape of their X-ray spectrum, which would tell us where the peak of their synchrotron emission was located.

    2017-03-01

    We address the problem of long-time asymptotics for the solutions of the Korteweg-de Vries equation under low regularity assumptions. We consider decaying initial data admitting only a finite number of moments. For the so-called ‘soliton region’, an improved asymptotic estimate is provided, in comparison with the one in Grunert and Teschl (2009 Math. Phys. Anal. Geom. 12 287-324). Our analysis is based on the dbar steepest descent method proposed by Miller and McLaughlin. Dedicated to Dora, Paolo and Sanja, with deep gratitude for their love and support.

    The Atlantic Forest is considered one of the world's biological diversity hotspots, and is increasingly threatened by the rapid destruction and fragmentation of its natural areas. The caddisflies (Trichoptera) of Itatiaia massif, an Atlantic Forest highland area, are inventoried and cataloged here. The catalog is based on examination of bibliographies, field work on many localities of Itatiaia massif (including Parque Nacional do Itatiaia — PNI), and the entomological collection Professor José Alfredo Pinheiro Dutra (DZRJ), Universidade Federal do Rio de Janeiro. A total of 92 species are recorded, representing about 17% of the known Brazilian Trichoptera fauna. Leptoceridae, Hydropsychidae, and Philopotamidae are the families most represented. The high species richness, as well as the remarkable patterns of species distribution, may be related to the characteristics of Mantiqueira mountain range. PMID:22958122

    Semple, John L., G.W. Kent Moore, Petros Koutrakis, Jack M. Wolfson, Paolo Cristofanelli, and Paolo Bonasoni. High concentrations of ozone air pollution on Mount Everest: health implications for Sherpa communities and mountaineers. High Alt Med Biol. 17:365-369, 2016.-Introduction: Populations in remote mountain regions are increasingly vulnerable to multiple climate mechanisms that influence levels of air pollution. Few studies have reported on climate-sensitive health outcomes unique to high altitude ecosystems. In this study, we report on the discovery of high-surface ozone concentrations and the potential impact on health outcomes on Mount Everest and the high Himalaya. Surface ozone measurements were collected during ascending transects in the Mount Everest region of Nepal with passive nitrite-coated Ogawa filter samplers to obtain 8-hour personal exposures (2860-5364 m asl). In addition, the Nepal Climate Observatory-Pyramid, a GAW-WMO Global Station sited in the Khumbu Valley (5079 m asl), collected ozone mixing ratios with photometric gas analyzer. Surface ozone measurements increased with altitude with concentrations that exceed 100 ppb (8-hour exposure). Highest values were during the spring season and the result of diverse contributions: hemispheric background values, the descent of ozone-rich stratospheric air, and the transport of tropospheric pollutants occurring at different spatial scales. Multiple climate factors, including descending stratospheric ozone and imported anthropogenic air masses from the Indo-Gangetic Plain, contribute to ambient ozone exposure levels in the vicinity of Mount Everest that are similar to if not higher than those reported in industrialized cities.

  4. Health education as education of the oppressed.

    PubMed

    van Wyk, N C

    1999-12-01

    Paolo Freire's theory of critical thinking shows remarkable similarities to the principles supported by health education. In his capacity as Brazilian educationalist, Freire emphasized man's active participation in his own development. Without this active involvement, growth and development become quite impossible to attain. Freire's theory is therefore generally well suited for use by those supporters of the currently emphasised actions of community empowerment and community involvement. Health education, and more particularly successful health education, is nothing more than community empowerment. It enables each individual, within a community, to take control of his/her own life and well-being. The health care professional cannot assign power and control to the individual; it can only be assumed by each individual within the community. In this regard it becomes evident that passive conveyance of the health care message, albeit from health care professional to individual recipient (in this instance to the patient), is of no use to the community, whereas active involvement of the individual displays greater success. According to Paolo Freire, health education should focus on collective knowledge, the latter being the result of the group dynamics, produced by discussion on past experiences, and the analyses there-of. The professional guides these dynamic processes, not only to identify needs regarding health education, but also to assist in making decisions on health. Ultimately each individual will then experience the responsibility for his/her own health. A discussion of the use of the theory of critical thinking, as well as the implementation there-of in practice, is provided.

    The reproduction in wax of anatomic specimens is considered a glorious Italian tradition, particularly in Florence. Indeed, the work of wax masters which was cultivated for ex-votos and statuary models, together with the development of anatomic studies under the guidance of Paolo Mascagni at the end of the eighteenth century, gave origin to several collections of waxes, among which the collection of the Museum of Anatomic Pathology holds undoubted interest. The so-called "leper", a full-scale reproduction by Luigi Calamai of a man affected with Norwegian scabies, a rare skin disease, is considered the symbol of the Museum.

    Cardinal Nicolas from Cues (1401-1464) was friend of Paolo Toscanelli and one of the first supporters of heliocentrism. He carved a tube in the south western wall of a room of the castle of Andraz. It was possibly used to calculate the date of the winter solstice, in order to evaluate the corrections needed to the Julian calendar then in use. The astronomical use of this tube is described. The accuracy achievable in the measurement of the solstice is surprising. It is possible that the tubes made by Gerbert of Aurillac (945-1003) were used with similar awareness.

    Golgi, Camillo

    2006-12-01

    This paper presents an "impossible interview" to Professor Camillo Golgi, placed in time in December 1906. The Italian Professor Golgi from Pavia has been awarded the Nobel Prize for Physiology or Medicine ex aequo with the Spanish anatomist Santiago Ramón y Cajal. Both scientists have obtained the award for their work on the anatomy of the nervous system. However, they have opposite views on the mechanisms underlying nervous functions. Golgi believes that the axons stained by his "black reaction" form a continuous anatomical or functional network along which nervous impulses propagate. Ramón y Cajal is the paladin of the neuron theory, a hypothesis questioned by Golgi in his Nobel lecture of Tuesday, December 11. After the ceremony, an independent journalist has interviewed Professor Golgi in the Grand Hotel in Stockholm. Excerpts about his education, his main scientific discoveries, and his personal life are here given (reconstructing the "impossible interview" on the basis of Golgi's original writings).

    Hastings, D. A. (Principal Investigator)

    1981-01-01

    Accomplishments with regard to the mapping and analysis of MAGSAT data for the investigation of correlations between the magnetic field characteristics of South American and African shields are reported. Significant results in the interpretation of the global total-field anomalies and the anomaly patterns of Africa and South America are discussed. The central position of the Brazilian shield tends to form a negative total-field anomaly, consistent with findings for shields in equatorial Africa. Sedimentary sequences in the Amazon basin and in the Rio de Janeiro-Sao Paolo areas exhibit positive anomalies, also consistent with equatorial Africa. Results for the Caribbean Sea and Guyana regions are also described.

  17. Colliding worlds: A journey in time and space through the solar system (Farinella Prize Lecture)

    NASA Astrophysics Data System (ADS)

    Marchi, S.

    2017-09-01

    The evolution of the interiors, surfaces, and atmospheres of solid bodies in the solar system is affected by interplanetary collisions. From Mercury to the outskirts of the solar system, collisions with leftover planetesimals -asteroids, comets and their debris- provide a primary evolutionary process. Impact craters mark this evolution and provide a diagnostic tool, which coupled with modeling and, when possible, sample analysis, allow us to unravel the ancient history of the solar system. In this prize talk, I will present a few selected cutting-edge research topics at the frontier between modeling and space exploration that without any doubt would have deeply interested the curious mind of Paolo Farinella.

    2018-02-19

    Here we provide reflections of and a tribute to John M. Olson, a pioneering researcher in photosynthesis. We trace his career, which began at Wesleyan University and the University of Pennsylvania, and continued at Utrech in The Netherlands, Brookhaven National Laboratory, and Odense University in Denmark. He was the world expert on pigment organization in the green photosynthetic bacteria, and discovered and characterized the first chlorophyll-containing protein, which has come to be known as the Fenna-Matthews-Olson (FMO) protein. He also thought and wrote extensively on the origin and early evolution of photosynthesis. We include personal comments from Brian Matthews, Raymond Cox, Paolo Gerola, Beverly Pierson and Jon Olson.

    This article studies a fragment on the conic sections that appear in the Codex Atlanticus, fols. 611rb/915ra. Arguments are put forward to assemble these two folios. Their comparison with the Latin texts available before 1500 shows that they derive from the De speculis comburentibus of Alhacen and the De speculis comburentibus of Regiomontanus, joined together in his autograph manuscript (Vienna, Oster. Nationalbibliothek, Cod. 5258). Having identified the sources, and discussed their mathematics, the issue of their transmission is targeted. It is shown that these notes were written by Paolo dal Pozzo Toscanelli, through whom they reached the notebooks of Leonardo da Vinci.

  9. Global Enhanced Vegetation Index

    NASA Technical Reports Server (NTRS)

    2002-01-01

    By carefully measuring the wavelengths and intensity of visible and near-infrared light reflected by the land surface back up into space, the Moderate-resolution Imaging Spectroradiometer (MODIS) Team can quantify the concentrations of green leaf vegetation around the world. The above MODIS Enhanced Vegetation Index (EVI) map shows the density of plant growth over the entire globe. Very low values of EVI (white and brown areas) correspond to barren areas of rock, sand, or snow. Moderate values (light greens) represent shrub and grassland, while high values indicate temperate and tropical rainforests (dark greens). The MODIS EVI gives scientists a new tool for monitoring major fluctuations in vegetation and understanding how they affect, and are affected by, regional climate trends.

    Pipolo, Tony

    2013-08-01

    The pervasive influence of the Oedipus complex on world culture is a given, yet throughout the long history of motion pictures only one major filmmaker has tackled the literary source that inspired Freud. The film, Edipo Re, directed by Italian poet, novelist, and social and political activist Pier Paolo Pasolini, not only reconstructs the myth and adapts Sophocles' tragedy, but uses both as a basis of cinematic autobiography. This paper is a detailed analysis of the formal, stylistic, and thematic dimensions of this film, illustrating the complex manner in which Pasolini interweaves myth, play, and autobiography into a unique cinematic achievement. This analysis is followed by speculations on the implications of the film's structure and techniques and on what they reveal about Pasolini's character, his sexual profile, and the ignominious murder that ended his life.

    Summary In September 1961, the First International Congress of Electromyography (EMG) was held at the University of Pavia. This event proved to be a sort of foundation stone for the further development of EMG as an organized field. Many of the most distinguished clinical neurophysiologists attended this congress and took an active part in it, delivering important lectures and scientific communications on the various aspects of EMG, including electroneurography. They included: Henri Gastaut, Fritz Buchthal, Jean Edouard Desmedt, Eric Kugelberg, Roger W. Gilliatt, John A. Simpson, Albrecht Struppler, Irena Hausmanowa-Petrusewicz, and Howard Edward Lambert. The congress was organized by Paolo Pinelli, at the time a young and brilliant clinical neurophysiologist who had learned the EMG procedure in Copenhagen under the guidance of Fritz Buchthal. Various scientific and social aspects of this important congress are outlined in this paper. PMID:22687169

    2014-12-01

    The conference Swift: 10 years of discovery was held in Roma at La Sapienza University on Dec. 2-5 2014 to celebrate 10 years of Swift successes. Thanks to a large attendance and a lively program, it provided the opportunity to review recent advances of our knowledge of the high-energy transient Universe both from the observational and theoretical sides. When Swift was launched on November 20, 2004, its prime objective was to chase Gamma-Ray Bursts and deepen our knowledge of these cosmic explosions. And so it did, unveiling the secrets of long and short GRBs. However, its multi-wavelength instrumentation and fast scheduling capabilities made it the most versatile mission ever flown. Besides GRBs, Swift has observed, and contributed to our understanding of, an impressive variety of targets including AGNs, supernovae, pulsars, microquasars, novae, variable stars, comets, and much more. Swift is continuously discovering rare and surprising events distributed over a wide range of redshifts, out to the most distant transient objects in the Universe. Such a trove of discoveries has been addressed during the conference with sessions dedicated to each class of events. Indeed, the conference in Rome was a spectacular celebration of the Swift 10th anniversary. It included sessions on all types of transient and steady sources. Top scientists from around the world gave invited and contributed talks. There was a large poster session, sumptuous lunches, news interviews and a glorious banquet with officials attending from INAF and ASI. All the presentations, as well as several conference pictures, can be found in the conference website (http://www.brera.inaf.it/Swift10/Welcome.html). These proceedings have been collected owing to the efforts of Paolo D’Avanzo who has followed each paper from submission to final acceptance. Our warmest thanks to Paolo for all his work. The Conference has been made possible by the support from La Sapienza University as well as from the ARAP

Although indications exist that theseexplosions are aspherical, direct evidence has still been missing.Late-time observations of SN 2003jd, a luminous hypernova, providesuch evidence. Recent Subaru and Keck spectra reveal double-peakedprofiles in the nebular lines of neutral oxygen and magnesium. Theseprofiles are different from those of known Type Ic supernovae, with orwithout a gamma-ray burst, and they can be understood if SN 2003jd wasan aspherical, axisymmetric explosion viewed from near the equatorialplane. If SN 2003jd was associated with a gamma-ray burst, we missedthe burst as it was pointing away from us.

  17. Red, White and Black: Colors of Beauty, Tints of Health and Cosmetic Materials in Early Modern English Art Writing.

    Alongside Richard Haydocke's translation of Giovanni Paolo Lomazzo's treatise on painting (1598), the article examines concepts of color concerning cosmetics, painting and complexion as they relate to aesthetics, artistic and medical practice in the sixteenth and seventeenth centuries. Beginning with white and red as ideal colors of beauty in Agnolo Firenzuola's Discourse on the beauty of women (1541), the essay places color in relation to major issues in art, medicine and empiricism by discussing beauty as a quality of humoral theory and its colors as visual results of physiological processes. Challenging the relation of art and nature, gender and production, Lomazzo's account of complexion and Haydocke's additions on cosmetic practices and face-painting provide key passages that shed light on the relation of cosmetics colors, art writing and artistic practices at the convergence of the body, art and medicine in the context of the emerging English virtuosi around 1600.

  18. Entropy: Thermodynamic definition and quantum expression

    Numerous expressions exist in the scientific literature purporting to represent entropy. Are they all acceptable? To answer this question, we review the thermodynamic definition of entropy, and establish eight criteria that must be satisfied by it. The definition and criteria are obtained by using solely the general, nonstatistical statements of the first and second laws presented in Thermodynamics: Foundations and Applications [Elias P. Gyftopoulos and Gian Paolo Beretta (Macmillan, New York, 1991)]. We apply the eight criteria to each of the entropy expressions proposed in the literature and find that only the relation S=-kTrρln ρ satisfies all the criteria, provided that the density operator ρ corresponds to a homogeneous ensemble of identical systems, identically prepared. Homogeneous ensemble means that every member of the ensemble is described by the same density operator ρ as any other member, that is, the ensemble is not a statistical mixture of projectors (wave functions).

    After more than 30 years, landmark progress has been made in the treatment of cancer, and melanoma in particular, with the success of new molecules such as ipilimumab, vemurafenib and active specific immunization. After the first congress in December 2010, the second edition of “Melanoma Research: a bridge from Naples to the World” meeting, organized by Paolo A. Ascierto (INT, Naples, Italy), Francesco M. Marincola (NIH, Bethesda, USA), and Nicola Mozzillo (INT, Naples, Italy) took place in Naples, on 5–6 December 2011. We have identified four new topics of discussion: Innovative Approaches in Prevention, Diagnosis and Surgical Treatment, New Pathways and Targets in Melanoma: An Update about Immunotherapy, and Combination Strategies. This international congress gathered more than 30 international faculty members and was focused on recent advances in melanoma molecular biology, immunology and therapy, and created an interactive atmosphere which stimulated discussion of new approaches and strategies in the field of melanoma.

    In Italy, 5 millions migrants live and work. Among them, the employment rate is much higher in comparison with the Italians' one (75% versus 62%). The well known "healthy migrant effect" is confirmed by statistics from the National Institute for Statistics: according to it, migrants access the National Health System for pregnancy and delivery and for accidents. The chronic pathology is not a major concern. Moreover, their work ability is generally complete, without any limitation. Nevertheless, migrants seem to represent a vulnerable subgroup with regard to the risk of 1) occupational injuries: this is strongly linked with the risk of Tetanus infection; 2) disorders of the metabolism, like hyperglycaemia and hyperlipemia, which is linked to a higher cardiovascular risk. In this light data from health surveillance carried out by the International centre for Rural Health of the San Paolo University Hospital in agricultural setting in the Region of Lombardy and the participation of the Centre itself to the Promovax EC-cofunded project are presented.

    2010-01-01

    In seventeenth-century Rome a popular financial scheme made it crucial to establish if pregnancy or childbirth had caused a woman's death. Courts sought medical advice, and this prompted physicians to reconsider the issues. Their disagreements provide historians with evidence from which to reassess received views of early modern doctors' involvement with birthing bodies. Among others, Paolo Zacchia intervened, revealing discord between physicians and jurists on how to establish the causes of death. One of his testimonies in a case shows more broadly how legal, medical, and lay views on pregnancy and childbirth intersected in courts of law. In Roman tribunals the very distinction between healthy and preternatural births was contentious, and the parties had an interest in having births either proved healthy in medical terms or construed as pathological. The controversies, the author argues, challenge historical expectations about early modern perceptions, including the boundaries between female and male, private and public, healthy and pathological.

    The interest for the study of Anatomy in Modena was particularly developed since the second half of eighteenth century, when the Duke Francesco III of Este promoted the reformation of the University and Antonio Scarpa was called from Padua to teach Anatomy. Scarpa promoted the building of the Anatomical Theatre, near the Grande Spedale, that was inaugurated in 1776. On the same year, the School of Obstetrics opened and determined the constitution of a first Cabinet or Obstetric Museum in a room next to the Theatre. After the Restoration, between 1817 and 1818, the Archduke Francesco IV of Austria Este promoted the realization of an Anatomical Museum: a big organized room in a new floor built on the Theatre. Two more rooms were added in, 1839 and a fourth one in 1853, under the direction of Paolo Gaddi. Furthermore Gaddi's interest for ethnographic studies determined the opening of the Ethnographic Anthropological Museum in 1866.

The title was Gerberto and Borromini, in order to evidence the link between Gerbert (938 ca. - 1003) and the Ticinese architect who saved his tumb, during the restauration of the Cathedral of Rome St. John in Laterano in 1648. It is possibile that from his residence in the Lateran Gerbert could observe the stars with his tubes, which are presented by C. Sigismondi in this volume. During his trips to Italy, alone and following the archbishop Adalbero of Reims Gerbert could have passed in the Chiusa Valley and influence with his astronomical knowledges the builders of the Sacra of S. Michele, this is the subject of Laura C. Paladino study. Abbo of Fleury is contemporary to Gerbert and he had the same vast interests. He studied in England and they are presented together in the paper of Paolo Rossi. Veronica Regoli shows the link between Gerbert, Dante and Jerusalem.

    Over the last 30 years, significant advancements have led to the use of multifunctional materials and structures technologies in spacecraft systems. This includes the integration of adaptive structures, advanced composites, nanotechnology, and additive manufacturing technologies. Development of multifunctional structures has been directly influenced by the implementation of processes and tools for adaptive structures pioneered by Prof. Paolo Santini. Multifunctional materials and structures incorporating non-structural engineering functions such as thermal, electrical, radiation shielding, power, and sensors have been investigated. The result has been an integrated structure that offers reduced mass, packaging volume, and ease of integration for spacecraft systems. Current technology development efforts are being conducted to develop innovative multifunctional materials and structures designs incorporating advanced composites, nanotechnology, and additive manufacturing. However, these efforts offer significant challenges in the qualification and acceptance into spacecraft systems. This paper presents a brief overview of the technology development and successful insertion of advanced material technologies into spacecraft structures. Finally, opportunities and challenges to develop and mature next generation advanced materials and structures are presented.

    Handover, in particular between two shifts, is a crucial aspect of nursing for patient safety, aimed at ensuring continuity of care. During this process, several factors can affect quality of care and cause errors. This study aimed to assess quality of handovers, by validating the Handoff CEX-Italian scale. The scale was translated from English into Italian and the content validity index was calculated and internal consistency assessed. The scale was used in several units of the San Paolo Teaching Hospital in Milan, Italy. A total of 48 reports were assessed (192 evaluations). The median score was 6, interquartile range (IQR) [5;7] and was not influenced by specific (p=0.21) or overall working experience (p=0.13). The domains showing the lowest median values (median=6, IQR [4;8]) were context, communication, and organisation. Night to morning handovers obtained the lowest scores. CVI-S was 0.96, Cronbach's alpha was 0.79. The Handoff CEX-Italian scale is valid and reliable and it can be used to assess the quality of nurse handovers.

    Radiogenic ingrowth of Ca-40 due to decay of K-40 occurred early in the solar system history causing the Ca-40 abundance to vary within different early-former reservoirs. Marshall and DePaolo ] demonstrated that the K-40/Ca-40 decay system could be a useful radiogenic tracer for studies of terrestrial rocks. Shih et al. [3,4] determined 40K/40Ca ages of lunar granitic rock fragments and discussed the chemical characteristics of their source materials. Recently, Yokoyama et al. [5] showed the application of the K-40/Ca-40 chronometer for high K/Ca materials in ordinary chondrites (OCs). High-precision calcium isotopic data are needed to constrain mixing processes among early solar system materials and the time of planetesimal formation. To better constrain the solar system calcium isotopic compositions among astromaterials, we have determined the calcium isotopic compositions of OCs and an angrite. We further estimated a source K/Ca ratio for alkali-rich fragments in a chondritic breccia using the estimated solar system initial Ca-40/Ca-44.

    Radiocarbon dating of short-lived sample materials is a useful tool applied to date deposits of volcanic eruptions. Several archaeological sites discovered and excavated in Campania witnessed important volcanic eruptions, which occurred in the Copper and Middle Bronze Ages. These eruptions come from the Somma-Vesuvius complex and the Phlaegrean Fields caldera. At least four Plinian eruptions have been identified in the eruptive history of Somma-Vesuvius, interspersed by interplinian events, called protohistoric, which occurred between Avellino and Pompeii. At S. Paolo Belsito a stratigraphic sequence below Avellino and above the first two protohistoric events after Avellino were highlighted; while Nola (Naples) gives new information on the chronology of Avellino. Sites like Caivano and Gricignano D'Aversa, involved by the Agnano 3, Paleoastroni 2 and Agnano Monte Spina eruptions were highlighted and investigated. In this work, we want to clarify the chronology of some eruptions by comparing our results with previous data. Charcoal, bone and seed samples were collected, treated and measured at the CIRCE laboratory in Caserta.

    This contribution focuses on the history of Coca leaves and Cocaine in the second half of 19th century Europe. Even though, to date, no direct link has been established between the activities of the Milano physician Paolo Mantegazza, and the Göttingen chemist Friedrich Wöhler, it is not a mere coincidence that both published their findings in the same year, namely, 1859. Mantegazza authored the first treatise claiming that Coca had psychoactive qualities and touted its broad therapeutic faculties; he claimed that it should be introduced into European pharmacotherapy. In Wöhler's laboratory, cocaine was isolated from leaves by his pupil Alfred Niemann; later, Wilhelm Lossen refined and corrected Niemann's results. Narratives about medicinal drugs often streamline history into a story that starts with multiple meanings and impure matters and ends with well-defined substances, directed at clear-cut diseases and symptoms. In the case of Coca, however, the pure substance triggered no such process well into the 1880s, whereas the leaves continued to circulate as an exotic, pluripotent drug whose effects where miraculous and yet difficult to establish.

    The asteroid belt is a natural laboratory for studying chaos, as a large fraction of asteroids actually reside on chaotic orbits. Numerous studies over the past 25 years have unveiled a multitude of dynamical chaos-generating mechanisms, operating on different time-scales and dominating over different regions of the belt. In fact, the distribution of chaotic asteroids in orbital space can be largely understood as the outcome of the combined action of resonant gravitational perturbations and the Yarkovsky effect - two topics on which Paolo Farinella has made an outstanding contribution! - notwithstanding the fact that the different "flavors" of chaos can give rise to a wide range of outcomes, from fast escape (e.g. to NEA space) to slow (~100s My) macroscopic diffusion (e.g. spreading of families) and strange, stable-looking, chaotic orbits (ultra-slow diffusion). In this talk I am going to present an overview of these mechanisms, presenting both analytical and numerical results, and their role in understanding the long-term evolution and stability of individual bodies, asteroid groups and families.

    expected NE-SW and SE-NW structural trends and it has been designed to get 2D/3D images of the crustal structure at a regional scale. A denser 2D network of 35 OBSs has been deployed in the bay of Pozzuoli aimed at detecting and modeling reflected/converted waves from 1 the possible shallow to deep discontinuities beneath the Campi Flegrei caldera. The main target of this particular receiver lay-out is the detailed imaging of the magma chamber top, expected at 4-5 km depth, according to temperature measurements in wells and sparse seismic observations. About 5000 shots have been performed dur- ing the SERAPIS experiment, at an average spatial spacing of 125 m, for a total ship travel path of 620 km. All of the seismic lines have been re-sampled at least twice, using a staggered configuration, which results in a smaller source spacing (less than 65m). In the gulf of Pozzuoli the source array had a geometry of a 5x5 km grid, slightly shifted south with respect to the OBS array. Seismic signals produced by air- guns have been well detected up to 50-60 km distance and the whole Campi Flegrei, Ischia and Procida on-land networks have recorded high quality seismograms pro- duced by the gridded source array in the bay of Pozzuoli. Due to the extended and very dense source and receiver arrays used for SERAPIS, this campaign can provide an innovative contribution to the accurate reconstruction of the Campi Flegrei caldera structure and to the definition of its feeding system at depth. *SERAPIS group: Auger Emmanuel, Bernard Marie-Lise, Bobbio Antonella, Bonagura Mariateresa, Cantore Luciana, Convertito Vincenzo, D'Auria Luca, De Matteis Raffaella, Emolo Anto- nio, Festa Gaetano, Gasparini Paolo, Giberti Grazia, Herrero Andre, Improta Luigi, Lancieri Maria Flora, Nielsen Stefan, Nisii Vincenzo, Russo Guido, Satriano Clau- dio, Simini Mariella, Vassallo Maurizio, Bruno Pier Paolo, Buonocunto Ciro, Capello Marco, Del Pezzo Edoardo, Galluzzo Danilo, Gaudiosi Germana, Giuliana Alessio

    The cell is metabolically highly compartmentalized. Especially, mitochondria host many vital reactions in their different microcompartments. However, due to their small size, these microcompartments are not accessible by conventional microscopy. Here, we demonstrate that time-correlated single-photon counting (TCSPC) fluorescence lifetime-imaging microscopy (FLIM) classifies not only mitochondria, but different microcompartments inside mitochondria. Sensor proteins in the matrix had a different lifetime than probes at membrane proteins. Localization in the outer and inner mitochondrial membrane could be distinguished by significant differences in the lifetime. The method was sensitive enough to monitor shifts in protein location within mitochondrial microcompartments. Macromolecular crowding induced by changes in the protein content significantly affected the lifetime, while oxidizing conditions or physiological pH changes had only marginal effects. We suggest that FLIM is a versatile and completive method to monitor spatiotemporal events in mitochondria. The sensitivity in the time domain allows for gaining substantial information about sub-mitochondrial localization overcoming diffraction limitation.

    This article reports an open discussion that took place during the Keenan Symposium "Meeting the Entropy Challenge" (held in Cambridge, Massachusetts, on October 4, 2007) following the short presentations—each reported as a separate article in the present volume—by Seth Lloyd, Owen Maroney, Silviu Guiasu, Ping Ao, Jochen Gemmer, Bernard Guy, Gian Paolo Beretta, Speranta Gheorghiu-Svirschevski, and Dorion Sagan. All panelists and the audience were asked to address the following questions • Why is the second law true? Is it an inviolable law of nature? If not, is it possible to develop a perpetual motion machine of the second kind? • Are second law limitations objective or subjective, real or apparent, due to the nature of physical states or the representation and manipulation of information? Is entropy a physical property in the same sense as energy is universally understood to be an intrinsic property of matter? • Does the second law conflict with quantum mechanics? Are the differences between mechanical and thermodynamic descriptions of physical phenomena reconcilable? Does the reversible law of motion of hamiltonian mechanics and quantum mechanics conflict with the empirical observation of irreversible phenomena?

  7. Coenzyme Q biosynthesis and its role in the respiratory chain structure.

    Coenzyme Q (CoQ) is a unique electron carrier in the mitochondrial respiratory chain, which is synthesized on-site by a nuclear encoded multiprotein complex. CoQ receives electrons from different redox pathways, mainly NADH and FADH2 from tricarboxylic acid pathway, dihydroorotate dehydrogenase, electron transfer flavoprotein dehydrogenase and glycerol-3-phosphate dehydrogenase that support key aspects of the metabolism. Here we explore some lines of evidence supporting the idea of the interaction of CoQ with the respiratory chain complexes, contributing to their superassembly, including respirasome, and its role in reactive oxygen species production in the mitochondrial inner membrane. We also review the current knowledge about the involvement of mitochondrial genome defects and electron transfer flavoprotein dehydrogenase mutations in the induction of secondary CoQ deficiency. This mechanism would imply specific interactions coupling CoQ itself or the CoQ-biosynthetic apparatus with the respiratory chain components. These interactions would regulate mitochondrial CoQ steady-state levels and function.

    Spectroscopic and colorimetric analysis of a representative set of Dugès watercolor paintings was performed. These paintings were the result of scientific studies carried out by the zoologist Alfredo Dugès, who recorded the fauna of the Mexican Republic between 1853 and 1910. Micro-Raman spectroscopy, with an excitation wavelength of 830 nm, and colorimetric techniques were employed in order to understand if different colors with the same hue were reproduced using the same pigments. The color coordinates of the measured areas were obtained in the CIE L* a* b* color space. Raman analysis showed that, in some cases, to reproduce colors with the same hue the pigment employed was not the same. Pigments identified in the watercolors were vermilion, carbon-based black, lead white, gamboge and chrome yellow, Prussian and ultramarine blue. Some of these pigments have been used since ancient times, others as Prussian blue, chrome yellow and synthetic ultramarine blue arrived to the market at the beginning of the 18th and 19th centuries, respectively. Furthermore, regarding the white color, instead of left the paper unpainted, lead white was detected in the eye of a bird. The green color was obtained by mixing Prussian blue with chrome yellow. The results of this work show the suitability of using Raman spectroscopy for watercolor pigment analysis and colorimetric techniques to measure the color of small areas (246 μm × 246 μm) that was the case for the lead white pigment.

  11. Malingering and retrograde amnesia: the historic case of the Collegno amnesic.

    Assessment of feigned cognitive disorders is an important field of neuropsychology because of its applications to forensic settings. Strategies for detecting malingering in amnesia are available for anterograde amnesia. Less attention has been given to malingering in retrograde amnesia. The case of the 'Smemorato di Collegno' (The Collegno Amnesic) is probably the most famous case of malingered retrograde amnesia ever known in Italy. In 1926, a man who appeared to have lost all his autobiographical memories and identity spent nearly a year in the Collegno asylum of Turin without a name. He was later initially identified as Giulio Canella, Director of the 'Scuola Normale di Verona' who had disappeared during the war in 1916. He was suspected of later identified as being Mario Bruneri, a petty crook from Turin who played the part of an amnesic whose retrograde memory gradually returned. A lengthy investigation was required before this conclusion was reached. Several clinicians and renowned academics evaluated the case, but only Alfredo Coppola, diagnosed "malingered retrograde amnesia" using a method that was extremely innovative for the times. The aim of the present paper is to review the original cognitive evaluation and the strategies used for malingering detection in the "Collegno case". The outcome of the case is then discussed in the light of present-day forensic neuropsychology and the level of advancement of mental examination achieved in the 1920s in Europe is highlighted.

    This study's objective was to evaluate the role of psychological adjustment in the decision-making process to have an abortion and explore individual variables that might influence this decision. In this cross-sectional study, we sequentially enrolled 150 women who made the decision to voluntarily terminate a pregnancy in Maternity Dr. Alfredo da Costa, in Lisbon, Portugal, between September 2008 and June 2009. The instruments were the Depression, Anxiety and Stress Scale (DASS), Satisfaction with Social Support Scale (SSSS), Emotional Assessment Scale (EAS), Decision Conflict Scale (DCS), and Beliefs and Values Questionnaire (BVQ). We analyzed the data using Student's T-tests, MANOVA, ANOVA, Tukey's post-hoc tests and CATPCA. Statistically significant effects were accepted for p<0.05. The participants found the decision difficult and emotionally demanding, although they also identified it as a low conflict decision. The prevailing emotions were sadness, fear and stress; but despite these feelings, the participants remained psychologically adjusted in the moment they decided to have an abortion. The resolution to terminate the pregnancy was essentially shared with supportive people and it was mostly motivated by socio-economic issues. The different beliefs and values found in this sample, and their possible associations are discussed. Despite high levels of stress, the women were psychologically adjusted at the time of making the decision to terminate the pregnancy. However, opposing what has been previously reported, the women presented high levels of sadness and fear, showing that this decision was hard to make, triggering disruptive emotions.

    Conference logo The XXXV Symposium on Nuclear Physics was held at Hotel Hacienda Cocoyoc, Morelos, Mexico from January 3-6 2012. Conceived in 1978 as a small meeting, over the years and thanks to the efforts of various organizing committees, the symposium has become a well known international conference on nuclear physics. To the best of our knowledge, the Mexican Symposium on Nuclear Physics represents the conference series with longest tradition in Latin America and one of the longest-running annual nuclear physics conferences in the world. The Symposium brings together leading scientists from all around the world, working in the fields of nuclear structure, nuclear reactions, physics with radioactive ion beams, hadronic physics, nuclear astrophysics, neutron physics and relativistic heavy-ion physics. Its main goal is to provide a relaxed environment where the exchange of ideas, discussion of new results and consolidation of scientific collaboration are encouraged. To celebrate the 35th edition of the symposium 53 colleagues attended from diverse countries including: Argentina, Australia, Canada, Japan, Saudi Arabia and USA. We were happy to have the active participation of Eli F Aguilera, Eduardo Andrade, Octavio Castaños, Alfonso Mondragón, Stuart Pittel and Andrés Sandoval who also participated in the first edition of the Symposium back in 1978. We were joined by old friends of Cocoyoc (Stuart Pittel, Osvaldo Civitarese, Piet Van Isacker, Jerry Draayer and Alfredo Galindo-Uribarri) as well as several first time visitors that we hope will come back to this scientific meeting in the forthcoming years. The scientific program consisted of 33 invited talks, proposed by the international advisory committee, which nicely covered the topics of the Symposium giving a balanced perspective between the experimental and the theoretical work that is currently underway in each line of research. Fifteen posters complemented the scientific sessions giving the opportunity

    Antibodies or immunoglobulins are proteins of paramount importance in the immune system. They are extremely relevant as diagnostic, biotechnological and therapeutic tools. Their modular structure makes it easy to re-engineer them for specific purposes. Short of undergoing a trial and error process, these experiments, as well as others, need to rely on an understanding of the specific determinants of the antibody binding mode. In this article, we present a method to identify, on the basis of the antibody sequence alone, which residues of an antibody directly interact with its cognate antigen. The method, based on the random forest automatic learning techniques, reaches a recall and specificity as high as 80% and is implemented as a free and easy-to-use server, named prediction of Antibody Contacts. We believe that it can be of great help in re-design experiments as well as a guide for molecular docking experiments. The results that we obtained also allowed us to dissect which features of the antibody sequence contribute most to the involvement of specific residues in binding to the antigen. http://www.biocomputing.it/proABC. anna.tramontano@uniroma1.it or paolo.marcatili@gmail.com Supplementary data are available at Bioinformatics online.

    This article presents a clinical report of a cornual ectopic pregnancy as well as a five-year restrospective review of ectopic gestations at Hospital General de Matamoros Dr. Alfredo Pumarejo L, Tamaulipas, Mexico. The list with histopatological reports was checked up from January 2001 to May 2006. There were 66 results, of which only 31 files were complete. The presentation ages in these patients were between 16 and 39 years old, with a media of 25.6 years old and a mode of 21 years. The circumstances why patients attended to the hospital were: transvaginal bleeding and abdominal pain in 14 cases (45.1%), abdominal pain only in 12 cases (38.7%), and transvaginal bleeding only in five cases (16.2%). The clinical presentation was acute in 19 patients (61.3%), and it was insidious in 12 (38.7%). All women presented menstrual delay. Diagnoses were done by clinical findings in 12 women (38.7%), by clinical findings and ultrasonography in 18 (58.1%), and due to clinical findings and culdocentesis in just one patient (3.2%). Ectopic pregnancy was located in different places on each patient, such as: ampula, 24 cases (77.5%); isthmus, four patients (12.8%); fimbria, one case (3.2%); ovary, one woman (3.2%), and cornual in one patient (3.2%). Twenty-seven cases of broken ectopic pregnancies (87%), were found as transoperative findings, and the other four (13%) were not broken ectopic. There were not demises. Cornual ectopic pregnancy represents 1.5% of the ectopic gestations, as it is reported in the literature.

    Officially designated as one of WHO's Collaborating Centers for Nursing Development (CCND), the UP College of Nursing in the Philippines will take on a leading role in achieving "health for all" through primary health care (PHC). The 1978 Declaration of Alma-Ata called for the goal of health for all by the year 2000, and recognized the key role of the nursing profession in this effort. In order to be designated a WHO collaborating center, an institution must be able to provide scientific and technical leadership at the national and international level, must be a stable institution, and must have the capacity to contribute to WHO programs. A WHO collaborating center forms part of an international network of institutions. Having become such a center, the UP College will form part of the Global Network for Nursing Development, organized in March 1987. The Global Network's functions include: 1) coordinating activities and promoting technical cooperation; 2) disseminating and exchanging informational; 3) monitoring trends in health services development and assessing their implications for nursing development; 4) supporting research; 5) gathering support and resources; and 6) promoting the goals of nursing development. As part of the Global Network, the UP College has developed a 4-year plan to fulfill the network's functions. During the June 1989 inauguration of the CCND, the Philippine Secretary of Health, Dr. Alfredo R. A. Bengzon, noted the country's lopsided ratio of health personnel per population, and issued a challenge to the UP College to lead the country in accelerating nursing development.

    Background This study's objective was to evaluate the role of psychological adjustment in the decision-making process to have an abortion and explore individual variables that might influence this decision. Methods In this cross-sectional study, we sequentially enrolled 150 women who made the decision to voluntarily terminate a pregnancy in Maternity Dr. Alfredo da Costa, in Lisbon, Portugal, between September 2008 and June 2009. The instruments were the Depression, Anxiety and Stress Scale (DASS), Satisfaction with Social Support Scale (SSSS), Emotional Assessment Scale (EAS), Decision Conflict Scale (DCS), and Beliefs and Values Questionnaire (BVQ). We analyzed the data using Student's T-tests, MANOVA, ANOVA, Tukey's post-hoc tests and CATPCA. Statistically significant effects were accepted for p<0.05. Results The participants found the decision difficult and emotionally demanding, although they also identified it as a low conflict decision. The prevailing emotions were sadness, fear and stress; but despite these feelings, the participants remained psychologically adjusted in the moment they decided to have an abortion. The resolution to terminate the pregnancy was essentially shared with supportive people and it was mostly motivated by socio-economic issues. The different beliefs and values found in this sample, and their possible associations are discussed. Conclusion Despite high levels of stress, the women were psychologically adjusted at the time of making the decision to terminate the pregnancy. However, opposing what has been previously reported, the women presented high levels of sadness and fear, showing that this decision was hard to make, triggering disruptive emotions. PMID:24163799

    The aim of this case-control study was to obtain a comprehensive panel of genetic polymorphisms present only in genes (cytochrome P-450 1A1--CYP1A1 and catechol-O-methyl transferase--COMT) within the metabolic pathway of sex steroids and determine their possible associations with the presence or absence of cervical cancer. Genotypes of 222 women were analyzed: a) 81 with cancer of the cervix treated at the Cancer Hospital Alfredo Abram, between June 2012 and May 2013, with diagnosis confirmed surgically and/or through histomorphological examination; and b) 141 healthy women who assisted at the Endocrine Gynecology and Climacteric Ambulatory, Department of Gynecology, UNIFESP-EPM. These polymorphisms were detected by polymerase chain reaction amplification-restriction fragment length polymorphism analysis and visualized on 3% agarose gels stained with ethidium bromide. We found a significant association between the frequency of the CYP1A1 polymorphism and the development of cervical cancer. A statistical difference was observed between patient and control groups for CYP1A1 polymorphism genotype distributions (P < 0.05). However, no significant differences were found in the COMT gene polymorphism genotype distributions between the patient and control groups (P > 0.05) or between other risk variables analyzed. The CYP1A1 gene involved in the metabolic pathway of sex steroids might influence the emergence of pathological conditions such as cervical cancer in women who carry a mutated allele, and result in 1.80 and 13.46 times increased risk for women with heterozygous or homozygous mutated genotypes, respectively.

    The Acquired Immunodeficiency Syndrome (AIDS) constitutes a sub-epidemic in Brazil. Due to the increasing number of women infected by the virus, the vertical transmission increased substantially, and due to the lack of adequate prophylactic treatment, many children are infected and show manifestations of the disease in early ages. Multiple systems are affected by the HIV virus, and the skin is often the first organ to be involved. The objective of this study is to analyze the clinic, dermatological and epidemiological profiles of children carriers of the virus in the City of Manaus aiming at identifying the most frequent dermatoses that affect these children and try to relate these dermatoses to the immunologic deterioration. A study was conducted where children carriers of the HIV virus from the Fundação Alfredo da Matta and Fundação de Medicina Tropical were studied from March 2007 to July 2008. These children were submitted to dermatological and laboratorial exams such as viral load dosage and CD4+ and CD8+ counts. During the study period, 70 HIV + children were examined; all of them had AIDS and had been contaminated by vertical transmission. The average number of dermatoses by children was 1.73, and 95.5% had at least one dermatosis during the study period. The most frequent manifestations were atopic dermatitis (22.9%), childhood prurigo (20%) and warts (18,6%). Children with HIV/AIDS have more skin disorders than children without HIV/AIDS. There was no statistical difference between the children in the group using ARVT and the group that wasn't using it.

    Ca isotopes are used to study the accretion history of the Earth and terrestrial planets, but, Ca isotopic composition of the Bulk Silicate Earth (BSE) remains poorly constrained [1]. To better understand the Ca isotopic composition of BSE, we analyzed 22 well studied peridotite xenoliths from Tariat (Mongolia), Vitim (southern Siberia) and Udachnaya (Siberian Craton). These samples include both fertile and highly depleted garnet and spinel peridotites that show no or only minor post-melting metasomatism or alteration. Ca isotope measurements were done on a Triton-TIMS using double spike method at the Guangzhou Institute of Geochemistry, CAS. The data are reported as δ44/40Ca (relative to NIST SRM 915a). Results for geostandards are consistent with those from other laboratories. 2 standard deviations of SRM 915a analyses are 0.13‰ (n=48). δ44/40Ca of both and fertile and refractory peridotites range from 0.79 to 1.07‰ producing an average of 0.93±0.12‰ (2SD). This value defines the Ca isotopic composition of the BSE, which is consistent with the average δ44/40Ca of oceanic basalts ( 0.90‰)[2,3].

  7. Narrativity and enaction: the social nature of literary narrative understanding

    2014-01-01

    This paper proposes an understanding of literary narrative as a form of social cognition and situates the study of such narratives in relation to the new comprehensive approach to human cognition, enaction. The particular form of enactive cognition that narrative understanding is proposed to depend on is that of participatory sense-making, as developed in the work of Di Paolo and De Jaegher. Currently there is no consensus as to what makes a good literary narrative, how it is understood, and why it plays such an irreplaceable role in human experience. The proposal thus identifies a gap in the existing research on narrative by describing narrative as a form of intersubjective process of sense-making between two agents, a teller and a reader. It argues that making sense of narrative literature is an interactional process of co-constructing a story-world with a narrator. Such an understanding of narrative makes a decisive break with both text-centered approaches that have dominated both structuralist and early cognitivist study of narrative, as well as pragmatic communicative ones that view narrative as a form of linguistic implicature. The interactive experience that narrative affords and necessitates at the same time, I argue, serves to highlight the active yet cooperative and communal nature of human sociality, expressed in the many forms than human beings interact in, including literary ones.

    A major barrier to the practical utilization of large, complex models of biochemical systems is the lack of open-source computational tools to evaluate model behaviors over high-dimensional parameter spaces. This is due to the high computational expense of performing thousands to millions of model simulations required for statistical analysis. To address this need, we have implemented a user-friendly interface between cupSODA, a GPU-powered kinetic simulator, and PySB, a Python-based modeling and simulation framework. For three example models of varying size, we show that for large numbers of simulations PySB/cupSODA achieves order-of-magnitude speedups relative to a CPU-based ordinary differential equation integrator. The PySB/cupSODA interface has been integrated into the PySB modeling framework (version 1.4.0), which can be installed from the Python Package Index (PyPI) using a Python package manager such as pip. cupSODA source code and precompiled binaries (Linux, Mac OS/X, Windows) are available at github.com/aresio/cupSODA (requires an Nvidia GPU; developer.nvidia.com/cuda-gpus). Additional information about PySB is available at pysb.org. paolo.cazzaniga@unibg.it or c.lopez@vanderbilt.edu. Supplementary data are available at Bioinformatics online. © The Author(s) 2017.

    1995-04-01

    This article describes the legislative mandate for the development of primary health care (PHC) in the Philippines and provides a discussion of the attempts made to realize the goals of that mandate. Two major Department of Health thrusts are delineated: 1) from 1986 to 1991 Under-Secretary Alfredo Bengzon sought to deemphasize the implementation of primary health care in favor of an approach which sought to forge partnerships with nongovernmental organizations (NGOs) to realize a concept of "Community Health Development" and 2) from 1992 to 1995, Secretary Juan Flavier restored attention to the implementation of PHC which would be operational under the guidance of local government units. The difference in the two approaches is primarily a difference in their manner of execution. Despite some problems, the first initiative achieved important goals such as 1) implementing an information system to allow targeting of areas for social development, 2) organizing the First National Convention of NGOs for Health, 3) encouraging collaborative activities with NGOs, and 4) support of the activities of Barangay Health Workers (BHWs). The second initiative involved recognition of additional volunteer health workers; following community organizing as a basic approach for empowerment; expanding the prior initiatives; and making plans to identify model PHC barangays, monitor levels of PHC implementation, and prepare a BHW operational manual. This review ends by considering various issues and offering recommendations which include: 1) spelling out the role of local chief executives, 2) adopting a single terminology to describe the current approach, 3) defining the role of the BHW (multipurpose worker or health worker), 4) adopting a convergence of efforts strategy, 5) monitoring levels of PHC, 6) documenting the PHC implementation process, 7) dealing with program sustainability issues, and 8) improving the management of local health facilities.

    The biocultural ethic recovers an understanding of the vital links between the life habits of the coinhabitants (humans and other-than-human) that share a habitat. The ″3Hs″ formal framework of the biocultural ethics provides a conceptual and methodological tool to understand and to better manage complex eco-social or biocultural systems in heterogeneous regions of the planet. From the global bioethics originally proposed by V.R. Potter, the integration of theory and praxis promoted by Alfredo Pradenas in the Bioethics Society of Chile, and the conceptual framework of biocultural ethics (including traditions of philosophical thought, scientific and Amerindians), I develop a comparative analysis of: 1. an ecosystemic and intercultural concept of the human body, 2. an intercultural understanding of health with complementary Western and Native American medicinal practices, and 3. an appreciation and respect for the fundamental links among the life habits, the habitats where they take place, and the well-being and identity of the communities of cohabitants. Implicit links in the ″3Hs″ biocultural ethics are present in the archaic meanings of the term ethos. This understanding retrieves a primordial root in the genesis of Western ethics, which did not start bounded to how to inhabit or dwell, but also considered where to inhabit and with whom to co-inhabit. I propose to restore the complexity and breadth of the concept of ethics originated in Ancient Greece, to reaffirm the common roots of bioethics and environmental ethics contained in Potter's global bioethics, and to incorporate the systemic and contextual perspective of the biocultural ethic that values biological and cultural diversity (and their interrelationships), to sustain a conception of human health interconnected with the sustainability of the biosphere.

    The relationship between subclinical hypothyroidism and depression is still controversial. Our objective was to compare the prevalence of depressive symptoms and major depressive disorder in a population of patients affected by subclinical hypothyroidism and a control group without thyroid disease. The authors enrolled 123 consecutive outpatients affected by subclinical hypothyroidism undergoing follow-up at the endocrinology department of San Paolo Hospital in Milan and 123 controls without thyroid disease under the charge of general physicians.All patients and controls underwent an evaluation by means of a psychiatric interview; Hamilton Rating Scale for Depression (HAM-D); Montgomery-Asberg Depression Rating Scale (MADRS); and serum thyroid stimulating hormone, free T4, and free T3 levels. Patients were also screened for thyroid peroxidase antibodies and thyroglobulin antibodies. Patients affected by subclinical hypothyroidism had a prevalence of depressive symptoms of 63.4% at HAM-D and 64.2% at MADRS; 22 patients (17.9%) had a diagnosis of depressive episode (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria). The control group had a prevalence of depressive symptoms of 27.6% at HAM-D and 29.3% at MADRS, and only seven controls had a diagnosis of depressive episode. The prevalence of depressive symptoms between these two groups was statistically different. This study underlines a strong association between subclinical hypothyroidism and depressive symptoms, which could have some important diagnostic and therapeutic implications in the clinical practice.

    The aim of the study was to compare lymphocytic infiltrations in early spontaneous abortions with those with signs of disruption at the chorio-decidual interface in elective abortions. Determinations were performed on preparations received at the Anatomy-Pathology Services of Ospedale San Paolo, Savona (Italy) in 2005. Immunohistochemistry studies were performed using antisera CD3, CD4 and CD14 with a DAB detection kit on a Ventana BenchMark automated slide staining system. The material was grouped into three classes: early spontaneous abortions (class 1); elective abortions with signs of disruption at the chorio-decidual interface (class 2); elective abortions without such signs (class 3). Preparations from classes 1 and 2 shared a similar picture of lymphocytic activation and the presence of macrophagic elements. The test results demonstrated that the proportion of the T cell population increased with the rise in CD8+ lymphocytes in both class 1 and class 2 preparations. The results indicate that T-cell-mediated immune activation may the cause or one of the causes of spontaneous abortion and that the effects of disruption at the chorio-decidual interface observed in elective abortion provide a clue to initial signs of loss of pregnancy. From the discovery of a population without evident signs of active abortion (elective abortion with a disturbed chorio-decidual interface) but with evidence of initial lymphocytic activation compared with that devoid of such signs (elective abortion) one can conjecture that lymphocytic activation is a major factor in the process leading to early spontaneous abortion.

    Low albumin levels and low lymphocyte counts are intra hospital conditions that exert a negative influence on prognosis, healing and length of hospitalization. The study aimed to analyze the correlation between low blood levels of albumin, low lymphocytes, and length of stay. The secondary aim was to identify other co-morbidities associated with prolonged hospital stay. Retrospective pilot study was conducted by analyzing anamnestic and biochemical data, related to 4038 patients admitted to ten wards of Hospital San Paolo (Milan), collected from July 1 st 2012 to December 31 st 2012. A statistical analysis was carried out using the Correlation method, Multivariate Analysis and Regression. Lymphocyte count and co-morbidities were evaluated in the whole cohort, albumin levels in 1437 patients. In the whole sample, low albumin levels and low lymphocyte counts were directly correlated to longer hospitalizations. The stratification of the results by department and diagnosis suggests that there is a higher correlation in certain subpopulations, and albumin shows a greater correlation with length of stay than lymphocytes. Also advanced age, high platelets, type of diagnosis, male gender and emergency admission led to longer hospitalizations. A routine check of albumin, lymphocytes and a spectrum of significant variables can provide precious information which can eventually lead to a shorter hospital stay. Knowledge of the general health status of a patient and the possibility to estimate his/her length of hospital stay are essential information for Clinical Governance, and for the improvement of internal services of hospitals on a large scale.

    Endoscopic transnasal approaches to the skull base have revolutionized the treatment of cerebrospinal fluid (CSF) fistulae, making repair less invasive and more effective compared with craniotomy or extracranial techniques. This study evaluated, retrospectively, the results of endoscopic repair of dural defects with the use of mucoperiostal grafts taken from the lower turbinate. Between January 1997 and January 2007, 125 cases of anterior skull base CSF fistulae were treated endoscopically at the Instituto Felippu de Otorrinolaringologia, Sao Paolo, Brazil, and at the Department of Otolaryngology of the University Hospital "Ospedali Riuniti", Foggia, Italy. Fistula closure was achieved by overlay apposition of a lower turbinate mucoperiostal graft fixated with fibrin glue and Surgicell. The etiology of the fistula was accidental trauma in 41 cases, iatrogenic trauma in 29, skull base tumour in 12, and spontaneous in 43. The site of the defect was the sphenoid sinus in 43 patients, the cribriform plate in 42, the anterior ethmoid roof in 21, the posterior ethmoid roof in 17, and the posterior wall of the frontal sinus in 2. The success rate at first attempt was 94.4%; the 7 cases of postoperative recurrent CSF leakage involved patients presenting with spontaneous fistula and elevated intracranial pressure; 5 of these had a body-mass index > 30 and 3 suffered from diabetes mellitus. In our hands, the success rate of endoscopic fistula repair was high, even in defects larger than 2 cm. Success rates may be further improved with accurate diagnosis of elevated intracranial pressure, a contributing factor to failure of spontaneous fistula repair.

    This paper describes how substance use features in the accounts of intimate partner violence (IPV) perpetrators in treatment in England and Brazil. The aim of the research was to better understand cross cultural constructions of IPV perpetration amongst men in treatment for substance use. Semi-structured interviews were conducted with 40 men in community substance use treatment in Sao Paolo, Brazil and London and the South East of England who had reported IPV perpetration in a questionnaire survey. A thematic, narrative analysis was carried out of men's explanations for IPV perpetration. Three types of narratives were distinguished: (i) disputes, centred on substance use, that escalate to IPV perpetration; (ii) IPV perpetration that is explained by uncharacteristic loss of control, as a result of intoxication; and (iii) IPV perpetration provoked by a perceived betrayal, in which substance use is incidental. In all types of accounts hegemonic principles of male and female roles and behaviour provided a context for and make IPV perpetration explicable. Substance use and IPV are culturally constructed and contextually defined. Understanding the meaning-making of substance using IPV perpetrators has implications for the treatment of both substance abuse and IPV.

    In 2009, Dr. Paolo Zamboni proposed chronic cerebrospinal venous insufficiency (CCSVI) as a possible cause of multiple sclerosis (MS). Although his theory and the associated treatment ("liberation therapy") received little more than passing interest in the international scientific and medical communities, his ideas became the source of tremendous public and political tension in Canada. The story moved rapidly from mainstream media to social networking sites. CCSVI and liberation therapy swiftly garnered support among patients and triggered remarkable and relentless advocacy efforts. Policy makers have responded in a variety of ways to the public's call for action. We present three different perspectives on this evolving story, that of a health journalist who played a key role in the media coverage of this issue, that of a health law and policy scholar who has closely observed the unfolding public policy developments across the country, and that of a medical ethicist who sits on an expert panel convened by the MS Society of Canada and the Canadian Institutes of Health Research to assess the evidence as it emerges. This story raises important questions about resource allocation and priority setting in scientific research and science policy. The growing power of social media represents a new level of citizen engagement and advocacy, and emphasizes the importance of open debate about the basis on which such policy choices are made. It also highlights the different ways evidence may be understood, valued and utilized by various stakeholders and further emphasizes calls to improve science communication so as to support balanced and informed decision-making.

    To analyse the accuracy and reproducibility of photogrammetry in detecting thoracic abnormalities in infants born prematurely. Cross-sectional study. The Premature Clinic at the Federal University of São Paolo. Fifty-eight infants born prematurely in their first year of life. Measurement of the manubrium/acromion/trapezius angle (degrees) and the deepest thoracic retraction (cm). Digitised photographs were analysed by two blinded physiotherapists using a computer program (SAPO; http://SAPO.incubadora.fapesp.br) to detect shoulder elevation and thoracic retraction. Physical examinations performed independently by two physiotherapists were used to assess the accuracy of the new tool. Thoracic alterations were detected in 39 (67%) and in 40 (69%) infants by Physiotherapists 1 and 2, respectively (kappa coefficient=0.80). Using a receiver operating characteristic curve, measurement of the manubrium/acromion/trapezius angle and the deepest thoracic retraction indicated accuracy of 0.79 and 0.91, respectively. For measurement of the manubrium/acromion/trapezius angle, the Bland and Altman limits of agreement were -6.22 to 7.22° [mean difference (d)=0.5] for repeated measures by one physiotherapist, and -5.29 to 5.79° (d=0.75) between two physiotherapists. For thoracic retraction, the intra-rater limits of agreement were -0.14 to 0.18cm (d=0.02) and the inter-rater limits of agreement were -0.20 to -0.17cm (d=0.02).

    Starting from a Fokker-Planck description of particle transport, which is valid when the scattering is forwardly peaked and the energy change in scattering is small, we systematically obtain an approximate diffusionlike equation for the particle density by eliminating the direction variable {bold {cflx {Omega}}} with an elimination scheme based on Zwanzig{close_quote}s projection operator formalism in the interaction representation. The elimination procedure closely follows one described by Grigolini and Marchesoni [in {ital Memory Function Approaches to Stochastic Problems in Condensed Matter}, edited by Myron W. Evans, Paolo Grigolini, and Guiseppe P. Parravicini, Advances in Physical Chemistry, Vol. 62 (Wiley-Interscience, New York,more » 1985), Chap. II, p. 29], but with a different projection operator. The resulting diffusion equation is correct up to the second order in the coupling operator between the particle direction and position variable. The diffusion coefficients and mobility in the resulting diffusion equation depend on the initial distribution of the particles in direction and on the path length traveled by the particles. The full solution is obtained for a monoenergetic and monodirectional pulsed point source of particles in an infinite homogeneous medium. This solution is used to study the penetration and the transverse and longitudinal spread of the particles as they are transported through the medium. Application to diffusive wave spectroscopy in calculating the path-length distribution of photons, as well as application to dose calculations in tissue due to an electron beam are mentioned. {copyright} {ital 1997} {ital The American Physical Society}« less

  3. Giuseppe Sergi. The portrait of a positivist scientist.

    PubMed

    Cerro, Giovanni

    2017-12-30

    Giuseppe Sergi (1841-1936) was one of the most important anthropologists and psychologists of the age of positivism and this article focuses on three domains of his scientific research: degeneration, eugenics and race. His concept of degeneration is defined as the development of special forms of human adaptation to the environment. This issue is closely related to his theory of the "stratification of character", which had a profound impact on Italian psychiatry and criminal anthropology in the late nineteenth century. Thus, special emphasis is placed on the differences between Sergi and Cesare Lombroso regarding their definitions of criminality and genius. Concerning eugenics, the article analyzes Sergi's key role in the Italian context, discussing his eugenic program based on both repression and education. His remedies against the spread of degeneration included not only radical and repressive measures, but also the improvement of popular education and the living conditions of the working class. In the field of physical anthropology, the article examines Sergi's morphological method of classifying ethnic groups. Although sharply criticized in Italy and abroad, this method had two major effects. First, it led to the definitive split between Sergi and Paolo Mantegazza and to the foundation of the Societá Romana di Antropologia in 1893. Second, it was the starting point for Sergi's theory of Mediterranean "stock", which claimed that European populations were of African origin in contrast to contemporary theories of Aryan supremacy. The article ends with a look at the heated debate over Sergi's Mediterraneanism during the period of Fascism.

    Purpose To examine the association between waist circumference (WC) and body mass index (BMI) on disability among older adults from Latin America and the Caribbean. Methods Cross-sectional, multicenter city study of 5,786 subjects aged 65 years and older from the Health, Well-Being and Aging in Latin America and the Caribbean Study (SABE) (1999-2000). Sociodemographic variables, smoking status, medical conditions, BMI, WC, and activities of daily living (ADL) were obtained. Results Prevalence of high WC (>88 cm) in women ranged from 48.5% (Havana) to 72.7% (Mexico City), while among men (>102 cm) it ranged from 12.5% (Bridgetown) to 32.5% (Santiago). The associations between WC and ADL disability were “J” shaped, with higher risks of ADL disability observed above 110 cm for women in Bridgetown, Santiago, Havana, and Montevideo. The association in Sao Paulo is plateau with higher risk above 100 cm, and the association in Mexico City is closer to linear. Among men the associations were “U” (Bridgetown, Sao Paulo, and Havana), “J” shaped (Montevideo), plateau (Santiago), and closer to linear in Mexico City (Figure 3). When WC and BMI were analyzed together, we found that participants from Sao Paolo, Santiago, Havana, and Montevideo in the overweight or obese category with high WC were significantly more likely to report ADL disability after adjusting for all covariates. Conclusion The findings of this study suggests that both general and abdominal adiposity are associated with disability and support the use of WC in addition to BMI to assess risk of disability in older adults.

    Incisional hernia is one of the main topics in the general surgery since there is not a unanimous consensus concerning to the best surgical methodology to adopt. It seems that prosthetic surgery is the best technique, even if responsible for the development of periprosthetic seroma. The aim of this study is to assess whether the preoperative abnormalities of the bio-humoral parameters may be considered as risk factors for seroma. From July 2016 to July 2017 at the "Policlinico Paolo Giaccone", Palermo, Department of Emergency Surgery, 56 patients included in this study, underwent laparotomic mesh repair. The inclusion criteria were: age > 18 years, incisional hernia W2R0 according to the Chevrel classification and a monoperator technique. The main variables were: sex, age, BMI, smoke, ASA score, and co-morbidities. Among the main serum-blood variables: natraemia, kalaemia, chloraemia, calcaemia, PCR, level of glucose, creatinine, albumin and proteins in the blood. The data were analyzed using SPSS software. Univariate analysis highlighted hypo- and hyper-natraemia, hyper-kalaemia, hypo-chloraemia, high levels of PCR, hyper-glycemia, low level of serum-blood albumin and proteins, as statistically significant variables. Multivariate analysis revealed a p<0.05 for PCR, hypo-albuminemia and total serum-blood-protein level. Alterations of pre-operative bio-humoral parameters could be associated to a greater risk of seroma development. A better understanding of such alterations may lead to more efficient risk stratification methods. This could be essential to better address the medical resources, reducing the post-operative complications and the outpatient controls as well as the risk associated to seroma.

    Prevalence and long-term outcome of epilepsy in tuberous sclerosis complex (TSC) is reported to be variable, and the reasons for this variability are still controversial. We reviewed the clinical characteristics of patients with TSC who were regularly followed since 2000 at the San Paolo Multidisciplinary Tuberous Sclerosis Centre in Milan, Italy. From patient charts we collected data about age at epilepsy onset, seizure frequency and seizure type, history of infantile spasms (IS), epileptic syndrome, evolution to refractory epilepsy or to seizure freedom and/or medication freedom, electroencephalography (EEG) features, magnetic resonance imaging (MRI) findings, cognitive outcome, and genetic background. Among the 160 subjects (120 adults and 40 children), 116 (72.5%) had epilepsy: 57 (35.6%) were seizure-free, and 59 (36.9%) had drug-resistant epilepsy. Most seizure-free patients had a focal epilepsy (89.5%), with 54.4% of them drug resistant for a period of their lives. Epilepsy onset in the first year of life with IS and/or focal seizures was characteristic of the drug-resistant group of patients, as well as cognitive impairment and TSC2 mutation (p < 0.05). A small group of patients (7 patients, 4.4%) experienced a seizure only once; all of them had normal cognition. Although epilepsy management can be challenging in TSC, more than one third of patients had their seizures controlled: through monotherapy in 56% and by polytherapy in 32%. Moreover, 12% of the patients became seizure-free and were off medication. Identifying predictive features of epilepsy and cognitive outcome can ensure better management for patients with TSC and delineate genotype-phenotype correlations.

    The discovery of the lymphatic system has a long and fascinating history. The interest in anatomy and physiology of this system paralleled that of the blood cardiocirculatory system and has been maybe obscured by the latter. Paradoxically, if the closed blood system appeared open in Galen's anatomy and physiology, and took a very long time to be correctly described in terms of pulmonary and general circulation by ibn Al-Nafis/Michael Servetus/Realdo Colombo and William Harvey, respectively, the open lymphatic system was incorrectly described as a closed circuit connected with arteries and veins. In ancient times only macroscopic components of the lymphatic system have been described, although misinterpreted, including lymph nodes and lacteals, the latter being easily identified because of their milk-like content. For about 15 centuries the dogmatic acceptance of Galen's notions did not allow a significant progress in medicine. After Vesalius' revolution in anatomical studies, new knowledge was accumulated, and the 17th century was the golden age for the investigation of the lymphatic system with several discoveries: gut lacteals (Gaspare Aselli), cloacal bursa (Hieronimus Fabricius of Acquapendente), reservoir of the chyle (Jean Pecquet), extra-intestinal lymphatic vessels (Thomas Bartholin and Olaus Rudbeck dispute), hepatic lymph circulation (Francis Glisson). In the Enlightenment century Frederik Ruysch described the function of lymphatic valves, and Paolo Mascagni provided a magnificent iconography of the lymphatic network in humans. In recent times, Leonetto Comparini realized three-dimensional reconstructions of the liver lymphatic vessels, and Kari Alitalo discovered the lymphatic growth factor/receptor system. Far from a complete understanding of its anatomy and function, the lymphatic system still needs to be profoundly examined. © 2017 Anatomical Society.

Laura C. Paladino presents the didactical activity of Gerbert as from Richer of Reims who completed his Historia Francorum in 998, before the election of Gerbert to the pontifical soil. Among these activities there is the teaching of astronomy and mathematics and the abacus, to which a special article of Jorge Nuno Silva is dedicated. The abacus increased dramatically the rapidity of the computations and some algoritms thaught by Gerbert and reported by his former student Bernelinus is very reliably invented by Gerbert himself, as Silva demostrates in his paper. Giancarlo Pani presents the relation between Galileo and Kepler, at the end of the humanistic period, showing interesting insights on the rather asymmetrical exchange of information between the two greater astronomer of 1600. Veronica Regoli presents the Cosmos of Dante, the ideal structure of the Divine Comedy. Patrick Demouy presents the new biography of Flavio G. Nuvolone where the great novelty is the noble origin of Gerbert from Carlat family, but before the marriage of his (presumed) father. His birth is shifted back to 938 with technical demostrations. Paolo Zanna compares the magisterium of Gerbert-Sylvester II and that one of John Paul II and pope Francesco. Finally C. Sigismondi presents the work and the activities of Pawel Max Maksym (1983-2013) who founded the Observatory &"Pope Sylvester II" in the town of Bukowiec, near Lodz, Poland.

    The design of hospital environments is determined by functional requirements and technical regulations, as well as numerous protocols, which define the structure and system characteristics that such environments need to achieve. In order to improve people's well-being and the quality of their experience within public hospitals, design elements (soft qualities) are added to those 'necessary' features. The aim of this research has been to experiment a new design process and also to create health care spaces with high environmental quality and capable to meet users' emotional and perceptual needs. Such needs were investigated with the help of qualitative research tools and the design criteria for one of these soft qualities - colour - were subsequently defined on the basis of the findings. The colour scheme design for the new San Paolo Hospital Emergency Department in Milan was used as case study. Focus groups were fundamental in defining the project's goals and criteria. The issues raised have led to believe that the proper procedure is not the mere consultation of the users in order to define the goals: users should rather be involved in the whole design process and become co-agents of the choices that determine the environment characteristics, so as to meet the quality requirements identified by the users themselves. The case study has shown the possibility of developing a designing methodology made by three steps (or operational tools) in which users' groups are involved in the choices, loading to plan the environments where compliance with expectations is already implied and verified by means of the process itself. Thus, the method leads to the creation of soft qualities in Healthcare.

    In Italy, the Human Papillomavirus (HPV) vaccination was implemented for twelve years old girls in 2007, but its coverage was lower than the recommended level. Sicily is one of the Italian administrative regions with lower vaccination coverage, with a value of 59% for those born in 1996 increasing to 62% coverage for those born in 1999. The aim of the study was to investigate factors associated with the refusal of HPV vaccination among young adult women of Palermo, Italy. The study was approved by the Ethics Committee of the Policlinico “Paolo Giaccone” Hospital (Palermo 1) and the questionnaire was validated in a convenience sample representing 10% of the young women. A cross-sectional study was conducted through the administration of a telephone questionnaire, consisting of 23 items on HPV infection and vaccination knowledge based on the Health Belief Model framework. The eligible population were young women (18–21 years old) who had at least a vaccination among all included in the Sicilian vaccination schedule, without starting or completing HPV vaccination. Overall, 141 young women were enrolled (response rate 22%). Among them, 84.4% were unvaccinated and 15.6% had at least one dose of the HPV vaccine. In multivariate analysis, the factors associated with the refusal of the HPV vaccination were a bachelor’s as the education level (OR = 10.2, p = 0.041), lower participation at school seminar on HPV (OR = 0.2, p = 0.047) and lower perception of HPV vaccine benefits (OR = 0.4, p = 0.048). Public health educational program focusing and tailored on benefits perception of HPV vaccine and HPV disease severity, carried out at school or during medical visits, can be useful to improve HPV vaccination uptake.

    Alkali-rich igneous fragments in the brecciated LL-chondrites, Krahenberg (LL5) [1], Bhola (LL3-6) [2], Siena (LL5) [3] and Yamato (Y)-74442 (LL4) [4-6], show characteristic fractionation patterns of alkali and alkaline elements [7]. The alkali-rich fragments in Krahenberg, Bhola and Y-74442 are very similar in mineralogy and petrography, suggesting that they could have come from related precursor materials [6]. Recently we reported Rb-Sr isotopic systematics of alkali-rich igneous rock fragments in Y-74442: nine fragments from Y-74442 yield the Rb-Sr age of 4429 plus or minus 54 Ma (2 sigma) for lambda(Rb-87) = 0.01402 Ga(exp -1) [8] with the initial ratio of Sr-87/Sr-86 = 0.7144 plus or minus 0.0094 (2 sigma) [9]. The Rb-Sr age of the alkali-rich fragments of Y-74442 is younger than the primary Rb-Sr age of 4541 plus or minus 14 Ma for LL-chondrite whole-rock samples [10], implying that they formed after accumulation of LL-chondrite parental bodies, although enrichment may have happened earlier. Marshall and DePaolo [11,12] demonstrated that the K-40 - Ca-40 decay system could be an important chronometer as well as a useful radiogenic tracer for studies of terrestrial rocks. Shih et al. [13,14] and more recently Simon et al. [15] determined K-Ca ages of lunar granitic rocks, and showed the application of the K-Ca chronometer for K-rich planetary materials. Since alkali-rich fragments in the LL-chondritic breccias are highly enriched in K, we can expect enhancements of radiogenic Ca-40. Here, we report preliminary results of K-Ca isotopic systematics of alkali-rich fragments in the LL-chondritic breccias, Y-74442 and Bhola.

    The present study aimed to provide practical guidelines for palliative treatment of advanced carcinoma of the pancreas (CAP) with the 2D technique. Fifteen patients with locally advanced CAP consecutively treated with radiation therapy at the Radiation Oncology Center, Research and Care Foundation 'Giovanni Paolo II' (Campobasso, Italy) underwent computed tomography simulation in supine position. Definition of the clinical target volume (CTV) included the head and body of the pancreas, and the retropancreatic space. The planning target volume was defined by adding a margin of 14 mm to the CTV in the cranio-caudal direction and of 11 mm in radial direction. For each patient, 3 treatment plans were calculated using a cobalt source, 6 MV photons and 15 MV photons (box technique). Beams were drawn using the primary collimators without using multileaf collimators, and progressively optimized in order to respect the minimum dose (D min >90%) constraint. Once the final plan was achieved, distances of the fields edges from a set of reference points (bony or duodenal landmarks) were measured. Using this technique, 15 anterior-posterior and postero-anterior (AP-PA) beams and 15 pairs of lateral-lateral (LL) beams were defined for the different patients. Finally, the single minimal AP-PA and LL beams able to include the 15 sets of AP-PA and LL beams were defined. The results of this analysis are reported in tabular form. Guidelines are provided for treatment based on cobalt unit or Linear accelerator (both 6 and 15 MV photons). This study provides information regarding field size and position. A dosimetric study has been planned to identify the dose to be administered with this technique taking into account current dose-volume constraints.

However, questions still remain regarding the quality of data being collected in these countries. We used ethnographic, mapping and computer simulation studies to identify/address areas of threat to near miss events for data quality in two cancer trial sites in Brazil. Two sites in Sao Paolo and Rio Janeiro were evaluated using ethnographic observations of workflow during subject enrolment and data collection. Emerging themes related to threats to near miss events for data quality were derived from observations. They were then transformed into workflows using UML-AD and modeled using System Dynamics. 139 tasks were observed and mapped through the ethnographic study. The UML-AD detected four major activities in the workflow evaluation of potential research subjects prior to signature of informed consent, visit to obtain subject́s informed consent, regular data collection sessions following study protocol and closure of study protocol for a given project. Field observations pointed to three major emerging themes: (a) lack of standardized process for data registration at source document, (b) multiplicity of data repositories and (c) scarcity of decision support systems at the point of research intervention. Simulation with policy model demonstrates a reduction of the rework problem. Patterns of threats to data quality at the two sites were similar to the threats reported in the literature for American sites.

    The Hawaii Scientific Drilling Project recovered core from a 3.5 km deep hole from the flank of Mauna Kea volcano, providing a long, essentially continuous record of the volcano's physical and petrologic development that has been used to infer the chemical and physical characteristics of the Hawaiian mantle plume. Determining a precise accumulation rate via 40Ar/39Ar dating of the shield-stage tholeiites, which constitute 95-98% of the volcano's volume is challenging. We applied40Ar/39Ar dating using laser- and furnace-heating in two laboratories (Berkeley and Curtin) to samples of two lava flows from deep in the core (˜3.3 km). All determinations yield concordant isochron ages, ranging from 612 ± 159 to 871 ± 302 ka (2σ; with P ≥ 0.90). The combined data yield an age of 681 ± 120 ka (P = 0.77) for pillow lavas near the bottom of the core. This new age, when regressed with 40Ar/39Ar isochron ages previously obtained for tholeiites higher in the core, defines a constant accumulation rate of 8.4 ± 2.6 m/ka that can be used to interpolate the ages of the tholeiites in the HSDP core with a mean uncertainty of about ±83 ka. For example at ˜3300 mbsl, the age of 664 ± 83 ka estimated from the regression diverges at the 95% confidence level from the age of 550 ka obtained from the numerical model of DePaolo and Stolper (1996). The new data have implications for the timescale of the growth of Hawaiian volcanoes, the paleomagnetic record in the core, and the dynamics of the Hawaiian mantle plume.

    Coenzyme Q (CoQ, or ubiquinone) is a remarkable lipid that plays an essential role in mitochondria as an electron shuttle between complexes I and II of the respiratory chain, and complex III. It is also a cofactor of other dehydrogenases, a modulator of the permeability transition pore and an essential antioxidant. CoQ is synthesized in mitochondria by a set of at least 12 proteins that form a multiprotein complex. The exact composition of this complex is still unclear. Most of the genes involved in CoQ biosynthesis (COQ genes) have been studied in yeast and have mammalian orthologues. Some of them encode enzymes involved in the modification of the quinone ring of CoQ, but for others the precise function is unknown. Two genes appear to have a regulatory role: COQ8 (and its human counterparts ADCK3 and ADCK4) encodes a putative kinase, while PTC7 encodes a phosphatase required for the activation of Coq7. Mutations in human COQ genes cause primary CoQ(10) deficiency, a clinically heterogeneous mitochondrial disorder with onset from birth to the seventh decade, and with clinical manifestation ranging from fatal multisystem disorders, to isolated encephalopathy or nephropathy. The pathogenesis of CoQ(10) deficiency involves deficient ATP production and excessive ROS formation, but possibly other aspects of CoQ(10) function are implicated. CoQ(10) deficiency is unique among mitochondrial disorders since an effective treatment is available. Many patients respond to oral CoQ(10) supplementation. Nevertheless, treatment is still problematic because of the low bioavailability of the compound, and novel pharmacological approaches are currently being investigated.

  19. Isaac Newton: Eighteenth-century Perspectives

    1999-05-01

    This new product of the ever-flourishing Newton industry seems a bit far-fetched at first sight: who but a few specialists would be interested in the historiography of Newton biography in the eighteenth century? On closer inspection, this book by one of the most important Newton scholars of our day turns out to be of interest to a wider audience as well. It contains several biographical sketches of Newton, written in the decades after his death. The two most important ones are the Eloge by the French mathematician Bernard de Fontenelle and the Italian scholar Paolo Frisi's Elogio. The latter piece was hitherto unavailable in English translation. Both articles are well-written, interesting and sometimes even entertaining. They give us new insights into the way Newton was revered throughout Europe and how not even the slightest blemish on his personality or work could be tolerated. An example is the way in which Newton's famous controversy with Leibniz is treated: Newton is without hesitation presented as the wronged party. Hall has provided very useful historical introductions to the memoirs as well as footnotes where needed. Among the other articles discussed is a well-known memoir by John Conduitt, who was married to Newton's niece. This memoir, substantial parts of which are included in this volume, has been a major source of personal information for Newton biographers up to this day. In a concluding chapter, Hall gives a very interesting overview of the later history of Newton biography, in which he describes the gradual change from adoration to a more critical approach in Newton's various biographers. In short, this is a very useful addition to the existing biographical literature on Newton. A J Kox

    Cataract is the leading cause of blindness in developing countries and identification of the barriers to accessing treatment is essential for developing appropriate public healthcare interventions. To evaluate the barriers to cataract surgery after diagnosis and assess the postoperative outcomes in Sao Paolo State, Brazil. This prospective study evaluated cataract patients from 13 counties in São Paulo State in 2014. Cataract was diagnosed in the community by a mobile ophthalmic unit and patients were referred to a hospital for management. Gender, age, distance to the hospital and local municipal health structure were evaluated as possible barriers. Data were analyzed for postoperative outcomes and the impact on blindness and visual impairment. Six hundred patients were diagnosed with cataract with a mean age of 68.8±10.3 years and 374 (62.3%) were females. Two hundred and fifty-four (42.3%) patients presented to the referral hospital. One hundred forty-four (56.7%) underwent surgery, 56 (22.0%) decided not to undergo surgery, 40 (15.7%) required only YAG-Laser and 14 (5.5%) required a spectacle prescription only. Visual acuity increased statistically significantly from 1.07±0.73 logMAR at presentation to 0.25±0.41 logMAR at the final visit after intraocular lens implantation (p=0.000). There was a statistically significantly decrease from 17 (11.8%) blind patients and 55 (38.2%) visually impaired patients at presentation to 2 (1.4%) and 5 (3.5%) patients respectively after treatment (p=0.000). Less than half of the individuals with cataract presented to the hospital for surgery. Among the patients who underwent treatment, there was an overall decrease in the number of blind individuals and visually impaired individuals. The barriers to cataract surgery were older age, greater distance to the hospital, municipalities with fewer inhabitants and less ophthalmic services.

    Megacrysts (large crystals of 2-15 mm in length) of plagioclases extracted from the lavas of the last three eruptions of southwestern Japan's Unzen volcano (AD 1663, AD 1792 and AD 1991-1995) have limited 87Sr/ 86Sr ratios of 0.70439-0.70454. Results of micro-drilling analyses indicated that three of eight megacrysts showed a gradual decrease in 87Sr/ 86Sr ratios from the core to the rim, whereas other megacrysts showed a homogeneous 87Sr/ 86Sr ratio. This relative homogeneity contrasts sharply to the wide variation of 87Sr/ 86Sr ratios of matrixes of the lavas of the last three eruptions (0.71417, 0.70467, 0.70447-0.70450, respectively). Most megacrysts show isotopic disequilibrium between their outer rims and their matrixes, suggesting that they did not grow in the host magmas. In addition, seven of the eight megacrysts of plagioclase also have similar trace element abundance ratios (La/Nd and Sr/Ba). Their similar chemical and isotopic compositions suggest that they crystallized from the same parent magma, which suggests to us that they were formed prior to or during the eruption in 1663. The isotopic ratios of the 1663 eruption lavas of 0.71417, however, rules out the possibility that it is the parent magma for the plagioclase megacrysts. The lavas erupted 4000 and 5000 years ago have 87Sr/ 86Sr ratios of 0.70454 and 0.70442, respectively, [Chen, C.-H., DePaolo, D.J., Nakada, S., Shieh, Y.-N., 1993. Relationship between eruption volume and neodymium isotopic composition at Unzen volcano. Nature 362, 831-834]; they are inferred to be of the parent magma because of their Sr isotope ratios. Consequently, the micro-analytical results seem to suggest that plagioclases with a single origin can be supplied to volcanic products of several different eruptions surviving several eruption events.

    Rock slope monitoring is a major aim in territorial risk assessment and mitigation. The use of "site specific" microseismic monitoring systems can allow to detect pre-failure signals in unstable sectors within the rock mass and to predict the possible acceleration to the failure. To this aim multi-scale geophysical methods can provide a unique tool for an high-resolution imaging of the internal structure of the rock mass and constraints on the physical state of the medium. We present here a cross-hole seismic tomography survey coupled with laboratory ultrasonic velocity measurements and determination of physical properties on rock samples to characterize the damaged and potentially unstable granitic cliff of Madonna del Sasso (NW, Italy). Results allowed to achieve two main advances, in terms of obtaining: i) a lithological interpretation of the velocity field obtained at the site, ii) a systematic correlation of the measured velocities with physical properties (density and porosity) and macroscopic features of the granite (weathering and anisotropy) of the cliff. A microseismic monitoring system developed by the University of Turin/Compagnia San Paolo, consisting of a network of 4 triaxial geophones (4.5 Hz) connected to a 12-channel data logger, has been deployed on the unstable granitic cliff. More than 2000 events with different waveforms, duration and frequency content were recorded between November 2013 and July 2014. By inspecting the acquired events we identified the key parameters for a reliable distinction among the nature of each signal, i.e. the signal shape (in terms of amplitude, duration, kurtosis) and the frequency content (maximum frequency content and frequency distribution). Four main classes of recorded signals can be recognised: microseismic events, regional earthquakes, electrical noises and calibration signals, and unclassified events (probably grouping rockfalls, quarry blasts, other anthropic and natural sources of seismic noise).

    Background The high rate of leprosy cases among children under 15 years of age in Brazil indicates ongoing transmission within the community. The identification of the new leprosy cases among contacts can help identify the source of infection and interrupt the transmission chain. This study aims to determine the detection rate of previously undiagnosed cases of leprosy among schoolchildren who are under 15 years of age living in Manaus, Amazonas, Brazil, and their possible source of infection by contact tracing. Methodology/Principal findings This was a school-based, cross-sectional study in which the identification of active leprosy cases was conducted in 277 out of 622 randomly selected public schools in Manaus, Amazonas, Brazil. Suspected cases of leprosy were referred to the Alfredo da Matta Foundation, a reference center for leprosy in Manaus. A total of 34,547 schoolchildren were examined, and 40 new leprosy cases were diagnosed. Among new cases, 57.5% were males, and 80.0% demonstrated paucibacillary leprosy. A total of 196 of 206 registered contacts were screened, and 52.5% of the newly diagnosed children’s cases had at least one positive household contact. In these contacts, grandparents (52.4%) were the most common co-prevalent cases, while 14.3% were uncles, 9.5% were parents and 9.5% were granduncles. Seven contacts (5.0%), including four siblings of child patients were newly diagnosed. Our data indicate that the prevalence is 11.58 per 10,000, which is 17 times higher than the registered rate. Conclusions/Significance This study suggests that the detection rate of leprosy among schoolchildren may have remained unchanged over the past thirty years. It also indicates that that active case finding is necessary for reaching the World Health Organization’s goals of zero detection among children, especially in endemic areas where the prevalence of leprosy is obscure. Moreover, we assert that all children must have their household contacts examined in

    The systematic approach of the pediatric patient with recurrent upper airway obstruction (RUAO) must be based on a through clinical history, physical examination, and the adequate use of the laboratory and diagnostic procedures, which must complement the correct identification of the causes of UAO and its interrelation with comorbid conditions as allergic rhinitis, rhinosinusitis and adenoiditis, with or without significant hypertrophy. this work, is to propose the study protocol of the patient with recurrent upper airway obstruction used in our own Instituto Privado de Alergia, Inmunología y Vías Respiratorias. We studied in a prospective fashion, a cohort of 117 pediatric patients, 12 years old and under, with clinical complaints of RUAO. 2/3 of these patients had a suggestive cytology pattern of nasal allergy and infection at the same time, following the method proposed by Dr. Alfredo Jalowayski from UC San Diego. The use of conventional radiology (lateral neck x ray) in the diagnosis of hypertrophy/hyperplasia of adenoidal tissue is useful and give us an orientation regarding the adenoidal size in 75% of the patients; nevertheless, it should not be considered as the most sensible diagnostic procedure to decide the best therapeutic option. If this study shows a decrease in diameter of the airway between the hard palate and the adenoidal shadow of 20% or more, we should proceeded with a flexible rhinopharyngoscopy to evaluate not only the real size of the adenoidal tissue, its mucosal appearance and its relation within the posterior pharynx with the Eustaquian tube (oto-pharyngeal tube-OPT). The endoscopic procedure is easy to perform, even in small children and showed us that almost half of the patients with abnormal lateral X-ray, have at least some degree of OFT obstruction. Aside from these results, the nasopharyngoscope give us useful information about comorbid and or existing conditions such as allergic rhintis, nasal polyposis, status of the osteomeatal

Literacy is about 65% among adults. 6 years of education are compulsory. 40% are engaged in agriculture, 27% in services, and 16% in industry. The gross domestic product was $5.1 billion; per capita income was $1160. El Salvador's history has been marked by frequent revolutions. Almost every present since 1932 has been a military officer. In the more recent past (1969-80), Honduras and El Salvador fought over borders; a peace treaty was signed in 1980, but it was not until 1992 that the land in dispute was awarded by the International Court of Justice to Honduras. During the 1970, efforts by Duarte were made toward democratic reform, but fraud and corruption contributed to the rise of armed guerrilla warfare as a means to bring about change. There were rightist and leftists groups accelerating violence; event he Salvadoran armed forces engaged in lawlessness. The judicial system failed. Nicaragua after 1979 supplied arms and munitions to 5 guerrilla groups. Duarte returned to power and his junta initiated land reform and nationalized banks and marketing of coffee and sugar. The elections in 1982 led to the transfer of power to Alvaro Magana. The new constitution in 1983 appeased some, but land reforms still did not satisfy guerrillas. Duarte was elected again in 1984 and Alfredo Christiani in 1989 in a peaceful transfer of power. In 1991 and 1992 peace accords were signed with the guerrillas. During this 12-year

    Context. Blazars are astrophysical sources whose emission is dominated by non-thermal processes, typically interpreted as synchrotron and inverse Compton emission. Although the general picture is rather robust and consistent with observations, many aspects are still unexplored. Aims. Polarimetric monitoring can offer a wealth of information about the physical processes in blazars. Models with largely different physical ingredients can often provide almost indistinguishable predictions for the total flux, but usually are characterized by markedly different polarization properties. We explore, with a pilot study, the possibility to derive structural information about the emitting regions of blazars by means of a joint analysismore » of rapid variability of the total and polarized flux at optical wavelengths. Methods. Short timescale (from tens of seconds to a couple of minutes) optical linear polarimetry and photometry for two blazars, BL Lacertae and PKS 1424+240, was carried out with the PAOLO polarimeter at the 3.6 m Telescopio Nazionale Galileo. Several hours of almost continuous observations were obtained for both sources. Results. Our intense monitoring allowed us to draw strongly different scenarios for BL Lacertae and PKS 1424+240, with the former characterized by intense variability on time-scales from hours to a few minutes and the latter practically constant in total flux. Essentially the same behavior is observed for the polarized flux and the position angle. The variability time-scales turned out to be as short as a few minutes, although involving only a few percent variation of the flux. The polarization variability time-scale is generally consistent with the total flux variability. Total and polarized flux appear to be essentially uncorrelated. However, even during our relatively short monitoring, different regimes can be singled out. Conclusions. No simple scenario is able to satisfactorily model the very rich phenomenology exhibited in our data. As

    Abstract Colonization and infection by multidrug-resistant gram-negative bacilli (MDR GNB) in neonatal intensive care units (NICUs) are increasingly reported. We conducted a 5-year prospective cohort surveillance study in a tertiary NICU of the hospital “Paolo Giaccone,” Palermo, Italy. Our objectives were to describe incidence and trends of MDR GNB colonization and the characteristics of the most prevalent organisms and to identify the risk factors for colonization. Demographic, clinical, and microbiological data were prospectively collected. Active surveillance cultures (ASCs) were obtained weekly. Clusters of colonization by extended spectrum β-lactamase (ESBL) producing Escherichia coli and Klebsiella pneumoniae were analyzed by conventional and molecular epidemiological tools. During the study period, 1152 infants were enrolled in the study. Prevalences of colonization by MDR GNB, ESBL-producing GNB and multiple species/genera averaged, respectively, 28.8%, 11.7%, and 3.7%. Prevalence and incidence density of colonization by MDR GNB and ESBL-producing GNB showed an upward trend through the surveillance period. Rates of ESBL-producing E coli and K pneumoniae colonization showed wide fluctuations peaking over the last 2 years. The only independent variables associated with colonization by MDR GNB and ESBL-producing organisms and multiple colonization were, respectively, the days of NICU stay (odds ratio [OR] 1.041), the days of exposure to ampicillin–sulbactam (OR 1.040), and the days of formula feeding (OR 1.031). Most clusters of E coli and K pneumoniae colonization were associated with different lineages. Ten out of 12 clusters had an outborn infant as their index case. Our study confirms that MDR GNB are an increasing challenge to NICUs. The universal once-a-week approach allowed us to understand the epidemiology of MDR GNB, to timely detect new clones and institute contact precautions, and to assess risk factors. Collection of these data can be an

    In the 1450s, when Leonardo da Vinci was born, horoscopes were still based primarily on the 13th-century tables developed in the court of Alfonso el Sabio of Spain. By the 15th century European astronomers were computing revised forms of the tables. In Italy, for example, Giovanni Bianchini of Ferrara completed his Tabulae astronomicae in the 1440s. It was finally published posthumously in Venice in 1495. By the 1480s Domenico Maria Novara, a professor of astronomy in Bologna, was publishing annual prognostications of eclipses, conjunctions, and other celestial phenomena. Against this background of traditional astronomy in Italy, two Florentines recorded observations of the sun and moon, comets, and meteorology. Paolo dal Pozzi Toscanelli flourished in the first half of the 15th century and Leonardo da Vinci in the last half. Their observations of celestial phenomena were not primarily for astronomical purposes; they were spinoffs of other pursuits such as medicine, astrology, optics, engineering, and studies of light and shadow. As a physician and cartographer, Toscanelli practiced astrology, studied omens, observed comets and plotted their paths on homemade maps. He also was associated with the construction of a gnomon at the top of the Duomo to observe the summer solstice. It was this project that may have brought him into contact with the young artisan, Leonardo da Vinci. As a painter, Leonardo's approach to science and engineering was to observe, sketch and analyze. His interest in light and shadow led him to notice how the earth, moon and planets all reflect sunlight. His extant manuscripts have geometric sketches for eclipses and for the phenomenon known as "old moon in new moon's arms." Unfortunately, because neither Toscanelli nor Leonardo published their observations, they made no impact on the history of astronomical thought or observation. Their contemporaries did not know or write about their work. Astronomers in the 16th century did not know about

    Although the contribution to anatomical illustration by Vesalius and his followers has received much attention, less credit has been given to Veslingius and particularly Fabricius. By 1600, Fabricius had amassed more than 300 paintings that together made the Tabulae Pictae, a great atlas of anatomy that was highly admired by his contemporaries. Many of his new observations were incorporated into subsequent books, including those by Casserius, Spighelius, Harvey and Veslingius. Also of importance were the Tabulae by Eustachius (1552), which, although only published in 1714, greatly influenced anatomical wax modelling. In 1742, Pope Benedict XIV established a Museum of Anatomy in Bologna, entrusting to Ercole Lelli the creation of several anatomical preparations in wax. Felice Fontana realised that the production of a large number of models by the casting method would make cadaveric specimens superfluous for anatomical teaching and in 1771 he asked the Grand Duke to fund a wax-modelling workshop in Florence as part of the Natural History Museum, later known as La Specola. Fontana engaged Giuseppe Ferrini as his first modeller and then the 19-year-old Clemente Susini who, by his death in 1814, had superintended the production of, or personally made, more than 2000 models. In 1780, the Austrian Emperor Joseph II visited La Specola and ordered a great number of models for his Josephinum museum; these were made by Fontana with the help of Clemente Susini and supervised by the anatomist Paolo Mascagni. It is, however, in Cagliari that some of Susini’s greatest waxes are to be found. These were made when he was free of Fontana’s influence and were based on dissections made by Francesco Antonio Boi (University of Cagliari). Their distinctive anatomical features include the emphasis given to nerves and the absence of lymphatics in the brain, a mistake made on earlier waxes. The refined technical perfection of the anatomical details demonstrates the closeness of the

    Context. Blazars are astrophysical sources whose emission is dominated by non-thermal processes, typically interpreted as synchrotron and inverse Compton emission. Although the general picture is rather robust and consistent with observations, many aspects are still unexplored. Aims. Polarimetric monitoring can offer a wealth of information about the physical processes in blazars. Models with largely different physical ingredients can often provide almost indistinguishable predictions for the total flux, but usually are characterized by markedly different polarization properties. We explore, with a pilot study, the possibility to derive structural information about the emitting regions of blazars by means of a joint analysismore » of rapid variability of the total and polarized flux at optical wavelengths. Methods. Short timescale (from tens of seconds to a couple of minutes) optical linear polarimetry and photometry for two blazars, BL Lacertae and PKS 1424+240, was carried out with the PAOLO polarimeter at the 3.6 m Telescopio Nazionale Galileo. Several hours of almost continuous observations were obtained for both sources. Results. Our intense monitoring allowed us to draw strongly different scenarios for BL Lacertae and PKS 1424+240, with the former characterized by intense variability on time-scales from hours to a few minutes and the latter practically constant in total flux. Essentially the same behavior is observed for the polarized flux and the position angle. The variability time-scales turned out to be as short as a few minutes, although involving only a few percent variation of the flux. The polarization variability time-scale is generally consistent with the total flux variability. Total and polarized flux appear to be essentially uncorrelated. However, even during our relatively short monitoring, different regimes can be singled out. Conclusions. No simple scenario is able to satisfactorily model the very rich phenomenology exhibited in our data. As

    The 1305 Ga Kiglapait Intrusion of coastal Labrador records the crystallization of troctolite through olivine gabbro to magnetite- and apatite-bearing rocks to monoclinic sanidine- mesoperthite-ferrosyenite below an inverted stratigraphy of a thin Upper Border Zone. The crystallization history was about 1 Ma. ¶The evolutionary history of Kiglapait feldspars in an 8.4 km thick magma chamber runs from plagioclase An70 at 5 kbar and 1250°C, cooling through to ferrosyenite with mesoperthite and two feldspars at 3 kbar and 1,000°C. The residual magma encountered the binodal solvus and finished crystallizing as an azeotrope with plagioclase (Or 21, An 15) and sanidine (Or 52, An 8) in liquid (Xor = 1/3; An 11). Cooling in the subsolidus brought the feldspars to compositions An15-Or 3, An0-Or 80-85 at 800-730°C. Metastable mesoperthite on the coherent solvus in various stages of late equilibration persists in the local assemblages. Arrested to complete feldspar symplectites suggest the local presence of a vapor phase. ¶Splits of the final Or-rich feldspar were found by mass spectrometry to have a dominant quantity of Rb and 87Sr/86Sr along with % amounts of Ba; in contrast, the plag fraction has very low Rb and 87Sr/86Sr. The estimated timing of the isotopic segregation was plausibly continuous with major-element fractionation or perhaps at the moment(s) of exsolution. ¶The cooling record of the solidified intrusion at 3 kbar is shown by 40Ar/39Ar data to have been rapid, reaching an ambient temperature near 240°C within the first 20 Ma, compared to the ambient country-rock temperature before intrusion of 350°C. The difference suggests a late uplift of the region after the Kiglapait magmatism. ¶Contributions from Y. Yu, T. Krogh, M. Hamilton, D. Lindsley, D. DePaolo, M. Jercinovic and S.R.

  16. Impacts and Ophiolites: A Way to Recognize Large Terrestrial Impact Basins?

    That Chicxulub Crater is located on ~35 km thick continental crust is apparently inconsistent with oceanic crustal/upper mantle geochemical signatures detected globally in the KT boundary impact layer [1-5 and unpublished Cr isotope data from the Yin lab at UC Davis] since introduction of the Alvarez hypothesis [6]. Apparent excavation and ejection of mafic/ultramafic target rock by the KT boundary impact might imply an additional KT impact site involving oceanic lithosphere. We speculate: 1) The Greater Antilles island chain ophiolite belt marks the rim of a ~700 km diameter impact basin, deformed and dismembered from an originally circular form by at least 50 million years of left lateral shear on the North American-Caribbean transform plate boundary; 2) Other ophiolite segments may similarly mark rims of large impact basins deformed to greater or lesser extent by, and serving as strain markers for, relative plate motions over geologic time; 3) The Greater Antilles/Chicxulub and Sulu Sea Basin/Spratly Island cases may constitute doublet craters of similar size ratio and separation distance; 4) Plate boundaries may be formed or modified by such impacts. Problems include: 1) The KT fireball layer should be tens of cm thick rather than a few mm thick [8-9]; 2) Impact basins of this size/scale are not expected in the Phanerozoic/Proterozoic [10]; References: [1] DePaolo D.

    Electronic screening and brief intervention (eSBI) apps demonstrate potential to reduce harmful drinking. However, low user engagement rates with eSBI reduce overall effectiveness of interventions. As "Digital Natives," young adults have high expectations of app quality. Ensuring that the design, content, and functionality of an eSBI app are acceptable to young adults is an integral stage to the development process. The objective of this study was to identify usability barriers and enablers for an app, BRANCH, targeting harmful drinking in young adults. The BRANCH app contains a drinking diary, alcohol reduction goal setting functions, normative drinking feedback, and information on risks and advice for cutting down. The app includes a social feature personalized to motivate cutting down and to promote engagement with a point-based system for usage. Three focus groups were conducted with 20 users who had tested the app for 1 week. A detailed thematic analysis was undertaken. The first theme, "Functionality" referred to how users wanted an easy-to-use interface, with minimum required user-input. Poor functionality was considered a major usability barrier. The second theme, "Design" described how an aesthetic with minimum text, clearly distinguishable tabs and buttons and appealing infographics was integral to the level of usability. The final theme, "Content" described how participants wanted all aspects of the app to be automatically personalized to them, as well as providing them with opportunities to personalize the app themselves, with increased options for social connectivity. There are high demands for apps such as BRANCH that target skilled technology users including young adults. Key areas to optimize eSBI app development that emerged from testing BRANCH with representative users include high-quality functionality, appealing aesthetics, and improved personalization. ©Joanna Milward, Paolo Deluca, Colin Drummond, Rod Watson, Jacklyn Dunne, Andreas Kimerg

    Several species of protozoa cause acute or chronic gastroenteritis in humans, worldwide. The burden of disease is particularly high among children living in developing areas of the world, where transmission is favored by lower hygienic standards and scarce availability of safe water. However, asymptomatic infection and polyparasitism are also commonly observed in poor settings. Here, we investigated the prevalence of intestinal protozoa in two small fishing villages, Porto Said (PS) and Santa Maria da Serra (SM), situated along the river Tietê in the State of São Paolo, Brazil. The villages lack basic public infrastructure and services, such as roads, public water supply, electricity and public health services. Multiple fecal samples were collected from 88 individuals in PS and from 38 individuals in SM, who were asymptomatic at the time of sampling and had no recent history of diarrheal disease. To gain insights into potential transmission routes, 49 dog fecal samples (38 from PS and 11 from SM) and 28 river water samples were also collected. All samples were tested by microscopy and PCR was used to genotype Giardia duodenalis, Blastocystis sp., Dientamoeba fragilis and Cryptosporidium spp. By molecular methods, the most common human parasite was Blastocystis sp. (prevalence, 45% in PS and 71% in SM), followed by D. fragilis (13.6% in PS, and 18.4% in SM) and G. duodenalis (18.2% in PS and 7.9% in SM); Cryptosporidium spp. were not detected. Sequence analysis revealed large genetic variation among Blastocystis samples, with subtypes (STs) 1 and 3 being predominant, and with the notable absence of ST4. Among G. duodenalis samples, assemblages A and B were detected in humans, whereas assemblages A, C and D were found in dogs. Finally, all D. fragilis samples from humans were genotype 1. A single dog was found infected with Cryptosporidium canis. River water samples were negative for the investigated parasites. This study showed a high carriage of intestinal

    Drought stress causes forest dieback that is often explained by two interrelated mechanisms, namely hydraulic failure and carbon starvation. However, it is still unclear which functional and structural alterations, related to these mechanisms, predispose to dieback. Here we apply a multi-proxy approach for the characterization of tree structure (radial growth, wood anatomy) and functioning (δ13C, δ18O and non-structural carbohydrates (NSCs)) in tree rings before and after drought-induced dieback. We aim to discriminate which is the main mechanism and to assess which variables can act as early-warning proxies of drought-triggered damage. The study was tailored in southern Italy in two forests (i.e., San Paolo (SP) and Oriolo (OR)) where declining and non-declining trees of a ring-porous tree species (Quercus frainetto Ten.) showing anisohydric behavior coexist. Both stands showed growth decline in response to warm and dry spring conditions, although the onset of dieback was shifted between them (2002 in SP and 2009 in OR). Declining trees displayed a sharp growth drop after this onset with reductions of 49% and 44% at SP and OR sites, respectively. Further, contrary to what we expected, declining trees showed a lower intrinsic water-use efficiency compared with non-declining trees after the dieback onset (with reductions of 9.7% and 5.6% at sites SP and OR, respectively), due to enhanced water loss through transpiration, as indicated by the lower δ18O values. This was more noticeable at the most drought-affected SP stand. Sapwood NSCs did not differ between declining and non-declining trees, indicating no carbon starvation in affected trees. Thus, the characterized structural and functional alterations partially support the hydraulic failure mechanism of dieback. Finally, we show that growth data are reliable early-warning proxies of drought-triggered dieback. © The Author 2017. Published by Oxford University Press. All rights reserved.

    The magma generation at Unzen volcano may be considered as the product of crustal material mixed with mantle magma accompanied by fractional crystallization (AFC). The magma in the Unzen volcano is estimated to consist of about 50-80% of residual magma ( F) and about 30-70% assimilated crustal material ( A) relative to the original magma. Concerning the 1991-1995 eruption, it is estimated that the magma formed as the result of mixing of about 50-60% crustal material and about 55-65% of residual magma. An alternative magma eruption model for the 1991-1995 eruption is proposed here. In the early stage, the isotopic characteristics of 1991 eruption are defined by AFC process in the deeper magma chamber. Later, the magma ascended through the conduit and quiescently stayed for a long time in a shallow reservoir before eruption. The minerals continuously crystallized as phenocrysts especially at the chilled top and outer margin in the shallow chamber. The crystallized phenocryst mush was reworked into the central part of the magma chamber by means of magma convection and rapid magma ascent. Therefore, the reaction between phenocrysts and melt occurs only in internal chemical disequilibrium in the magma chamber. In contrast, the isotopic compositions of the original magma shall be little influenced by the above processes throughout its eruptive history. The 1991-1995 eruptive rocks of the Unzen volcano show their characteristics in Sr and Nd isotopic values independent of their two previous eruptions. However, the isotopic values of early eruptive product could represent the original magma value. This result also supports the previous work of Chen et al. (1993) [Chen, C.H., DePaolo, D.J., Nakada, S., Shieh, Y.N., 1993. Relationship between eruption volume and neodymium isotopic composition at Unzen volcano. Nature 362, 831-834], that suggested the ɛNd of early or precursory eruptive products could be a qualitative indicator of the maximum size of a continuing or

    Brazil's capital city, Rio de Janeiro, has been called Latin America's slum capital, and is slowly losing its political position to Brasilia and its cultural and economic leadership to Sao Paolo. Rio's metropolitan area includes 14 municipalities and had a population of 9.64 million in 1984, making it Latin America's 4th largest and the world's 14th largest metropolitan area. The 452-square mile central city contains 5.35 million people. Projections predict that Rio will be the world's 9th largest city in the year 2000, with a population of 13.3 million. Rio encompasses sharp social and economic contrasts; population density varies from 30,686 to 124 people per square mile and per capita municipal budgets range from $100 to $12.50. Like most metropolitan areas, Rio's suburbs show its greatest growth. The peripheral municipalities which held only 24% of the population in 1940, now have about 45%. Low land prices and government housing attact poor families to these areas which tend to be economically sluggish. Rio's fertility rate (2.8%) is the lowest in Brazil (4.2%) and life expectancy is somewhat higher than the national average. Low fertility and declining migration result in small households and increasing age structure. 2.2 million households, with 3.8 persons on an average, and 1.3 million households, with 3.6 persons, inhabited the metropolitan area and its municipality, respectively. Less of Rio's population are black (10%) or of mixed descent (39%) than in the rest of Brazil; the population is 97% Brazilian-born. Most metropolitan homes are owner occupied, but Rio also has many highly visible slums. Rio has an 84% literacy rate; 5% of the population have university degrees. The area's geography requires massive daily movement by nearly 60% of the population, and several municpalities function largely as commuter towns. Service jobs (especially for women) account for 27% of all jobs with manufacturing and tourism next in importance. Median monthly income

    Factors predicting prescriptions of triple therapy were investigated in a large group of general practitioners in Italy. In the population treated by identified general practitioners, a cohort of newly diagnosed chronic obstructive pulmonary disease patients was extracted from IMS Health Longitudinal Database during the period 2010-2013. From the diagnosis, 1-year follow-up was evaluated. Thirty-two thousand forty-six newly diagnosed chronic obstructive pulmonary disease patients were evaluated (57.7% male, mean age 67 years). During 2 years prior to diagnosis less than 13% of patients were requested with a pulmonology evaluation and less than 5% with a spirometry; 65.1% cases were prescribed with a respiratory drug, which in 9.6% of cases was inhaled corticosteroid/long-acting β 2 -agonist fixed-dose combination. Two thousand and twenty eight patients (6.3% of the newly diagnosed chronic obstructive pulmonary disease patients) were treated with triple therapy during the first year of follow-up, whose 858 (42.3%) starting immediately, and 762 (37.6%) following an initial treatment with inhaled corticosteroid/long-acting β 2 -agonist fixed-dose combination. Being older, being requested with pulmonologist evaluation or spirometry, being prescribed with a inhaled corticosteroid/long-acting β 2 -agonist fixed-dose combination at diagnosis resulted independent predictors of triple therapy use. ENSURING CORRECT PRESCRIPTIONS FOR EARLY-STAGE DISEASE: An improved education program for doctors promoting correct use of medication for chronic lung disease is needed in Italy. Current guidelines state that inhaled corticosteroids (ICSs) should be reserved for patients with severe chronic obstructive pulmonary disease (COPD), but it appears that doctors do not always follow this advice.

    Herein, we measure the Ca isotope ratios ( 44 Ca/ 42 Ca and 43 Ca/ 42 Ca) in serum and bone samples collected from rats with chronic kidney disease (CKD) or diabetes mellitus (DM). For the serum samples, the isotope ratios are lower for the CKD (δ 44 Ca/ 42 Ca serum = 0.16 ± 0.11‰; 2SD, n = 6) and the DM (δ 44 Ca/ 42 Ca serum = -0.11 ± 0.25‰; 2SD, n = 7) rats than that for the control rats (δ 44 Ca/ 42 Ca serum = 0.25 ± 0.04‰; 2SD, n = 7). Bone samples from two distinct positions of 20 rats in total, namely, the center and proximal parts of the tibial diaphysis, are subject to Ca isotope analysis. The resulting δ 44 Ca/ 42 Ca values for the bone of the proximal part are about 0.3‰ lower than that for the serum samples from the same rats. The larger isotope fractionations between the serum and bone are consistent with previously reported data for vertebrate animals (e.g., Skulan and DePaolo, 1999), which suggests the preferential incorporation of lighter Ca isotopes through bone formation. For the bones from the control and CKD rats, there were no differences in the δ 44 Ca/ 42 Ca values between the positions of the bone. In contrast, the δ 44 Ca/ 42 Ca values of the bone for the DM rats were different between the positions of the bone. Due to the lower bone turnover rate for the DM rats, the δ 44 Ca/ 42 Ca for the middle of the diaphysis can reflect the Ca isotopes in the bone formed prior to the progression of DM states. Thus, the resulting δ 44 Ca/ 42 Ca values show a clear correlation with bone mineral density (BMD). This can be due to the release of isotopically lighter Ca from the bone to the serum. In the present study, our data demonstrate that the δ 44 Ca/ 42 Ca value for serum can be used as a new biomarker for evaluating changes in bone turnover rate, followed by changes in bone volume.

    Continued industrial development of the South Americas with increasing atmospheric emission of toxic trace metals has lead to a growing concern about possible effects on pristine ecosystem health. Concentration measurements of trace metals in ocean surface waters in the North Atlantic have successfully revealed the global extent of atmospheric pollution in the Northern Hemisphere during economical growth in the USA and Europe, suggesting a similar approach can be applied to the Southern Hemisphere. To this end, we determined concentrations of lead (Pb), antimony (Sb) and arsenic (As) using voltammetry in surface water samples of the South Atlantic Ocean collected during the third leg of the GEOTRACES West Atlantic Cruise. These elements are volatile and therefore most likely suitable tracer elements of industrial emissions from South America. The samples were not filtered and the solutions were acidified and UV digested. Total concentrations of Pb were detected. Detected As levels correspond to the sum of inorganic species (AsIII + AsV) plus the mono methyl arsenic acid (MMA) while the dimethyl arsenic acid (DMA) is not detected in such conditions. For Sb, detected levels correspond at least to the sum of inorganic fractions (SbIII + SbV). The measured concentrations for Pb varied from 6 to 23 pM. Concentrations were highest at -35° latitude and lowest at -40° and -50° latitude. We found a decreasing trend from about -35° latitude southwards. The average concentrations of As was 20 nM and of Sb 1.2 nM. Arsenic showed a more significant north to south trend than Sb. Arsenic concentration was highest at -23 ° latitude (21 nM) and the lowest at -43 ° latitude (17.7 nM). Antimony concentration was highest at -31 ° latitude (1.5 nM) and lowest at -35 ° latitude (1.0 nM). Our preliminary data suggests that the major industrial centres in Brazil (i.e., Sao Paolo, Rio de Janeiro) and Argentina (i.e., Buenos Aires) affect atmospheric metal fluxes to remote

    There will be ten participants: four ESA astronauts (Pedro Duque, Leopold Eyharts, Paolo Nespoli and Thomas Reiter), four Japanese astronauts from NASDA (Takao Doi, Koichi Wakata, Satoshi Furukawa and Aikihido Hoshide) and two NASA astronauts (Nicole Passonno Stott and Stephanie D. Wilson). The main objective of this training session is to prepare the astronauts for the tasks they will have to perform when the Japanese experiment module (JEM) and ESA's Columbus laboratory are docked with the core of the International Space Station over the years ahead. After completing their training and certification, the astronauts will be assigned to long-duration missions to the ISS. The advanced training at the EAC will focus on the Columbus systems and the Automated Transfer Vehicle (ATV). It will consist of 24 classroom lectures on the Columbus and ATV systems and 4 on payloads, and 2 sessions in the Columbus Trainer. Instructors are being provided by Astrium for the Columbus systems and Alenia Spazio for the ATV, with ESA/EAC staff as mentors for the Columbus payloads. The astronauts are scheduled to visit Astrium in Bremen on 30 August to get acquainted with the flight unit of the Columbus laboratory module currently undergoing integration. This group of astronauts started their advanced training in April 2001 at NASA's Johnson Space Center (JSC), Houston, where they attended a first course on the US segment of the International Space Station. This was followed by training on the JEM system at NASDA's Tsukuba Space Center, Japan, in December 2001 - January 2002 and additional training at the JSC in May 2002. At the beginning of next year the group will be returning to Tsukuba for training on Japanese payloads. Hands-on sessions on Columbus Payload Training Models are scheduled for the second half of 2003, again at ESA's European Astronaut Centre. On Thursday 5 September, between 16:30 and 18:30 hrs, the astronauts and other ESA specialists will be available for interviews

    The Hawaii Scientific Drilling Project, phase 2 (HSDP-2), recovered core from a ˜3.1-km-thick section through the eastern flanks of Mauna Loa and Mauna Kea volcanoes. We report results of 40Ar/39Ar incremental heating by broad-beam infrared laser of 16 basaltic groundmass samples and 1 plagioclase separate, mostly from K-poor tholeiites. The tholeiites generally have mean radiogenic 40Ar enrichments of 1-3%, and some contain excess 40Ar; however, isochron ages of glass-poor samples preserve stratigraphic order in all cases. A 246-m-thick sequence of Mauna Loa tholeiitic lavas yields an isochron age of 122 ± 86 kyr (all errors 2σ) at its base. Beneath the Mauna Loa overlap sequence lie Mauna Kea's postshield and shield sequences. A postshield alkalic lava yields an age of 236 ± 16 kyr, in agreement with an age of 240 ± 14 kyr for a geochemically correlative flow in the nearby HSDP-1 core hole, where more complete dating of the postshield sequence shows it to have accumulated at 0.9 ± 0.4 m/kyr, from about 330 to <200 ka. Mauna Kea's shield consists of subaerial tholeiitic flows to a depth of 1079 m below sea level, then shallow submarine flows, hyaloclastites, pillow lavas, and minor intrusions to core bottom at 3098 m. Most subaerial tholeiitic flows fail to form isochrons; however, a sample at 984 m yields an age of 370 ± 180 kyr, consistent with ages from similar levels in HSDP-1. Submarine tholeiites including shallow marine vitrophyres, clasts from hyaloclastites, and pillow lavas were analyzed; however, only pillow lava cores from 2243, 2614, and 2789 m yield reliable ages of 482 ± 67, 560 ± 150, and 683 ± 82 kyr, respectively. A linear fit to ages for shield samples defines a mean accumulation rate of 8.6 ± 3.1 m/kyr and extrapolates to ˜635 kyr at core bottom. Alternatively, a model relating Mauna Kea's growth to transport across the Hawaiian hot spot that predicts downward accelerating accumulation rates that reach ˜20 m/kyr at core bottom (DePaolo

By examing the chamber overpressure generated by injection of magma (Jellinek and DePaolo, 2003) and the overpressure related to magma buoyancy (Karlstrom et al, 2010), eruption during high-frequency magma input may be promoted by the magma buoyancy while an eruption during low-frequency input may be caused by injection of a large magma batch.

    Recent industrialization and urbanization in South America (SA) have notably exacerbated the air pollution with adverse impacts on human health and socio-economic systems. Consequently, there is a strong demand for developing ever-better assessment mechanisms to monitor the air quality at different temporal and spatial scales and minimize its damages. Based on previous achievements (e.g., MACC project in Europe and PANDA project in East Asia) we aim to design and implement an integrated system to monitor, analyze and forecast the air quality in SA along with its impacts upon public health and agriculture. An initiative will be established to combine observations (both satellite and in-situ) with advanced numerical models in order to provide a robust scientific basis for short- and long-term decision-making concerning air quality issues in SA countries. The main objectives of the project are defined as 3E: Enhancement of the air quality monitoring system through coupling models and observations, Elaboration of comprehensive indicators and assessment tools to support policy-making, Establishment of efficient information-exchange platforms to facilitate communication among scientists, authorities, stockholders and the public. Here we present the results of the initial stage, where a coarse resolution (50×50 km) set up of Weather Research and Forecast model with Chemistry (WRF-Chem) is used to simulate the air quality in SA considering anthropogenic, biomass-burning (based on MACCity, FINN inventories, respectively) and biogenic emissions (using MEGAN model). According to the availability of the observation data for Metropolitan Area of São Paulo, August 2012 is selected as the simulation period. Nested domains with higher resolution (15×15 km) are also embedded within the parent domain over the megacities (Sao Paolo and Rio de Janeiro in Brazil and Buenos Aires in Argentina), which account for the major anthropogenic emission sources located along coastal regions

Albano1, Rudolf Bentlage2, Hannah Drummond2, D.A. García-Ramos1, Martin Zuschin1 1 Department of Paleontology, University of Vienna, Austria 2 St. Lawrence University, Canton, New York 13617, USA Trace fossils left by predators in the skeleton of their prey are arguably one of the most powerful sources of direct data on predator-prey interactions available in the fossil record. Drill holes, especially those attributed to naticid and muricid gastropods, are unambiguous marks of predation and allow discriminating between successful and unsuccessful predation attempts (complete and incomplete holes, respectively). Latitude and water depth influence drilling frequency. We inspected death assemblages of an intertidal flat and of two subtidal (water depth between 6 and 20 m) sandy sites in the Persian (Arabian) Gulf, off the coast of the United Arab Emirates, to determine the patterns of predation on shelled molluscs along the depth gradient. The study is based on ~7,000 and ~60,000 shells from the intertidal and subtidal, respectively. Drilling Frequency (DF, the number of drilled individuals), Incomplete Drilling Frequency (IDF, number of incomplete drill holes), and Prey Effectiveness (ratio between the number of incomplete drill holes and the total number of drilling attempts) were used as metrics of drilling intensity. We observed major differences between the intertidal and subtidal study areas. Drilling frequencies were generally remarkably low and intertidal flats showed a much lower drilling frequency than the subtidal (1.4% and 6.7%, respectively). In the subtidal, we observed significant differences of drilling intensity among bivalve species and between the two sites. However, predation metrics did not correlate with environmental factors such as substrate type and depth, nor with species life

  3. An overview on the history of pedology and soil mapping in Italy

    NASA Astrophysics Data System (ADS)

    Calzolari, C.

    2012-04-01

    In Italy, the word pedology (pedologia) was introduced in a text book as synonym of soil science for the first time in 1904 by Vinassa de Regny. In the literature, the term cohabitates with the words agrology (agrologia), agro-geology (agro-geologia), agricultural geognostic (geognostica agraria), geopedology (geo-pedologia) used in different historical moments by differently rooted soil scientists. When early pedologists started with systematic studies of soils, their characteristics and geography, they were strongly influenced by their cultural background, mainly geology and agro-chemistry. Along the time, the soil concept evolved, as did the concept of pedology, and this is somehow witnessed by the use of different Italian words with reference to soil: suolo, terreno, terra. Differently from agro-chemists, early pedologists based the soil study on the field description of soil profile. This was firstly based on the vertical differentiation between humus rich layers and "inactive" layers and later on, as long as the discipline evolved, on the presence of genetic horizons. The first complete soil map of Italy is dated 1928. Its Author, the geologist De Angelis d'Ossat, was the president of the organising committee of the 1924 International Soil Conference of Rome, where the International Society of Soil Science was founded. The map was based on the geological map of Italy, drafted in scale 1:1,000,000 after the creation of the Kingdom of Italy in 1861. The internal disputes within the Geological Society, together with the scarce interest of most of geologists for soil, did not facilitate the birth of a central soil survey. Soil mapping was mainly conducted by universities and research institutes, and we had to wait until 1953 for a new soil map (scale 1:3,125,000) at national level to be realised by Paolo Principi, based on literature data. In 1966 a new 1:1,000,000 soil map of Italy was eventually published by a national committee, led by Fiorenzo Mancini. This

    to different degrees depending on region and cancer type. The major advances in cancer management that occurred up to 2007 seem to have resulted in improved survival in Europe. Likely explanations of differences in survival between countries include: differences in stage at diagnosis and accessibility to good care, different diagnostic intensity and screening approaches, and differences in cancer biology. Variations in socioeconomic, lifestyle, and general health between populations might also have a role. Further studies are needed to fully interpret these findings and how to remedy disparities.

    Mountain regions have a range of geological and geomorphological features that make them very attractive for tourism activities. As a consequence, increased human "pressure" causes impacts on geoheritage sites and higher geomorphological risks. These effects are magnified by active geomorphic processes characterizing mountains areas, highly sensitive to climate change. In term of "human sensitivity", several sociological surveys have shown that "perceived risk", not "real risk", influences people's behavior towards natural hazards. The same approach can be applied to geodiversity and geoheritage. Based on these assumptions, we considered the possible strategic roles played by diffusion of scientific research and application of new technologies: 1) to enhance awareness, either of geodiversity or environmental dynamics and 2) to improve knowledge, both on geoheritage management and natural risk reduction. Within the activities of the "ProGEO-Piemonte Project" (Progetti d'Ateneo 2011, cofunded by Universita? degli Studi di Torino and Compagnia di San Paolo Bank Foundation), we performed a systematic review of geodiversity and natural hazards information in the Piemonte Region (NW-Italy). Then we focused our attention on the Susa Valley, an area of the Western Alps where the geoheritage is affected by very active morphodynamics, as well as by a growing tourism, after the 2006 winter Olympics. The Susa Valley became one of the 9 strategic geothematic areas have been selected to represent the geodiversity of the Piemonte region, each characterized by high potential for enhancement of public understanding of science, and recreation activities supported by local communities. Then we contributed to the awareness-raising communication strategy of the "RiskNat project" (Interreg Alcotra 2007-2013, Action A.4.3) by synthesizing geoscience knowledge on the Susa Valley and information on slope instabilities and models/prevention measures/warning systems.

    consistent with that implied by the Nd isotope data from fine grained sediments reported for glacial intervals by DePaolo et al. (2006, EPSL, v. 298, pp. 394- 410). It is well known that much of the debris carried by icebergs is fine grained, and thus this provenance match suggests that it is likely that much of the fine grained material may also be carried to this site by icebergs.

    Andosols are young soils that shall know a successive evolution towards pedological types where the dominant pedogenetic processes are more evident. Vegetation and climate influence Andosols evolution to other order of soils. In cold and wet climates or on acid vulcanite under heavy leaching young Andosols could change into Podzols (Van Breemn and Buurman, 1998). Were investigated a Podzol soil (World References Base, 2014) at Zoniën (Belgium), were and an Andosol soil (World References Base, 2014) at Lago Laceno (Avellino, Italy). This study shows the data on the SOC (Soil Organic Carbon) fractionation in two profiles from two natural pine forest soils. Together with the conventional activities of sampling and analysis of soil profile were examined surveys meant to fractionation and characterization of SOC, in particular: Total Organic Carbon (TOC) and Total Extractable Carbon (TEC) soil contents were determined by Italian official method of soil analysis (Mi.P.A.F. (2000)). Different soil C fractions were also determined: Humic Acid Carbon (HAC), Fulvic Acid Carbon (FAC), Not Humic Carbon (NHC) and Humin Carbon (Huc) fractions were obtained by difference. In the whole profile, therefore, were also assayed cellulose and lignin contents. The aim of this work was to compare the distribution of different soil organic components in a podzol and a soil with andic properties. The data show great similarity, among the selected profiles, in the organic components distribution estudied.

    The effects of subsidence and subsequent landslides in mining areas are very frequent, the study examines the proposed mining area of Acquaresi (Sardinia South - West), interested in the years between 1991 and 2003 by major subsidence phenomena and consequent events landslides. The valley of Acquaresi is particularly important, not only for its mines, but also for the aspect related to the geomorphological evolution morphotectonic in the context of Paleozoic lithologies, which have a rectangular structure parallel to the coastline. To make measurements and analysis of the evolution of human morphostructural and throughout the industry, it was considered appropriate to create a three-dimensional model that would allow a synoptic view with the different information available to the industry. E 'was created a model using the points listed extrapolated from the Regional Technical Map scale 1:10,000, the map at scale 1:2000 dell'IGEA and the values of a detailed survey of the study area, measured at a scale 1: 500. How MicroStation CAD software was used, with whom it is made of a TIN high detail taking into account then is, if possible, of quoted points, roads, major infrastructure, contour lines (lines-intermediate-auxiliary), buildings and lines coast. The model was supported and shaped (draping) image obtained by integrating the color orthophotos of the area in 1:10,000 scale of the Autonomous Region of Sardinia and photos to scale 1:2,000 made to run dall'IGEA spa at the last event of the landslide. The use of aerial photographs, a scale similar to that of cartography, has allowed us to achieve excellent results by superimposing the frames of the areas of interest on models made, with views that appear to be consistent with the technical papers, with a maximum error of less than that of the reference mapping. Moreover, to emphasize the tectonic lineations, morphological aspects and changes in landscape and environment, it was considered appropriate to use a three-dimensional model, thanks to software used in this trial, with a high detail 3D visualization. Starting from the Regional Technical Map has been possible to realize the DEM file, then perform an interpolation with a point layer containing elevation values recorded separately and then superimpose the orthophoto to 3D surface. It was also decided to use a terrain model DTM knitted irregular TIN compared to a regular grid pattern GRID, because the first best response to the need to have a shirt that exploited all possible points present and identifiable in the territory. With the use of a TIN was thus possible to insert also the points detected by the GPS in the country to verify the area of detachment of the landslide, thus being able to increase the detail in the area of observation. Getting a noticeable "jump" quality: moving from a two-dimensional to a three-dimensional display. The model thus obtained has allowed a very good point of the area: they are easy to locate the outcrops of the different lithological structures, facilitating the study and evaluation for interventions of recovery.

Our hypothesis is that tutored theoretical-practical training is a more cost-effective option for teaching undergraduate students to detect caries lesions. If our hypothesis is confirmed, the use of laboratory training in conjunction with theoretical classes could be used as an educational strategy in Cariology to improve the development of undergraduate students' skills in the detection of caries lesions and clinical decision-making. ©Mariana Minatel Braga, Tathiane Larissa Lenzi, Fernanda Rosche Ferreira, Fausto Medeiros Mendes, Daniela Prócida Raggio, José Carlos Imparato, Marcelo Bonecker, Ana Carolina Magalhães, Linda Wang, Daniela Rios, Juliano Pelim Pessan, Cristiane Duque, Maria Augusta Bessa Rebelo, Ary Oliveira Alves Filho, Marina De Deus Moura Lima, Marcoeli Silva Moura, Alessandro Diogo De Carli, Mariane Emi Sanabe, Maximiliano Sergio Cenci, Elenara Ferreira Oliveira, Marcos Britto Correa, Rachel Oliveira Rocha, Julio Eduardo Zenkner, Pedroza Uribe Murisí, Stefania Martignon, Juan Sebastian Lara, Fatima Gabriela Aquino, Alfredo Carrillo, Chun Hung Chu, Chris Deery, David Ricketts, Paulo Melo, José Leopoldo Ferreira Antunes, Kim Rud Ekstrand, IuSTC Group.

  13. Using AMS to Help Interpret Glaciogenic Deposits of the Late Paleozoic Ice Age in the Parana Basin, Brazil

    Basin, Brazil. 19 fabrics were analyzed from seven different locations (Alfredo Wagner, Aurora, Cachoeira do Sul, Campo do Tenente, Ibare, Porto Amazonas, and Sao Gabriel), stretching across the states of Rio Grande do Sul, Santa Catarina, and Parana. While in most cases, AMS allowed us to delineate between the origins of diamictites, in other cases, it proved to be more difficult. In most cases, AMS measurements were beneficial in determining the direction of sediment transport. Our findings are consistent with past studies in which AMS was used to infer a variety of glaciogenic deposits, but also acts as a study case for the different types of fabrics that may develop as a result of Newtonian vs non-Newtonian sediment gravity flows. While flow directions along the southern margin of the basin are consistent with the inferred N/NW ice movement into the basin, some of the flow directions along the eastern margin are not, revealing deviations in topography. Flow directions obtained from mass transport deposits in the area stretching from Campo do Tenente to Porto Amazonas (an area in which different stratigraphic levels of glaciation are exposed) tend to show uniform flow to the south. This observation is consistent with other AMS studies of similar deposits within the area, suggesting the existence of a southward paleoslope, which strongly influenced subaqueous deposition throughout the extent of the Itarare Group.

    Rock slope monitoring is a major aim in territorial risk assessment and mitigation. The high velocity that usually characterizes the failure phase of rock instabilities makes the traditional instruments based on slope deformation measurements not applicable for early warning systems. The use of "site specific" microseismic monitoring systems, with particular reference to potential destabilizing factors, such as rainfalls and temperature changes, can allow to detect pre-failure signals in unstable sectors within the rock mass and to predict the possible acceleration to the failure. We deployed a microseismic monitoring system in October 2013 developed by the University of Turin/Compagnia San Paolo and consisting of a network of 4 triaxial 4.5 Hz seismometers connected to a 12 channel data logger on an unstable patch of the Madonna del Sasso, Italian Western Alps. The initial characterization based on geomechanical and geophysical tests allowed to understand the instability mechanism and to design a 'large aperture' configuration which encompasses the entire unstable rock and can monitor subtle changes of the mechanical properties of the medium. Stability analysis showed that the stability of the slope is due to rock bridges. A continuous recording at 250 Hz sampling frequency (switched in March 2014 to 1 kHz for improving the first arrival time picking and obtain wider frequency content information) and a trigger recording based on a STA/LTA (Short Time Average over Long Time Average) detection algorithm have been used. More than 2000 events with different waveforms, duration and frequency content have been recorded between November 2013 and March 2014. By inspecting the acquired events we identified the key parameters for a reliable distinction among the nature of each signal, i.e. the signal shape in terms of amplitude, duration, kurtosis and the frequency content in terms of range of maximum frequency content, frequency distribution in spectrograms.

    The papers published in this volume deal with historical and contemporary themes of physics and astronomy, always with the focus in didactics, as in the style of Gerbert of Aurillac, "rogatus a pluribus" (required by several students to write down the basics of new sciences). 1. Christopher Columbus in the voyage to America of 1492 discovered the deviation of the Magnetic North from the Celestial North; his measurements could have been done with the technology available to Gerbert, here we present the astronomical aspects of them. 2. On the meridian line of Santa Maria degli Angeli (1702) we repeated the experiences of Cassini in characterizing the refraction of the atmosphere by the difference between observed and calculated positions of the center of the Sun: 3. The collection of astronomical instruments in the Vatican Museums gives the opportunity to present the role of Astronomy in Catholic Church, starting from the calculation of Easter, present in the Chair of Hyppolitus. 4. The Eucharistic Miracle in Lanciano is dated VIII century AD, and the recognition of 1574 found the miracle of weights, where the five drops weigthed like one only. A discussion on that result is made on the light of sensibility of the scales of that time, which does not depart from the one of Gerbert's time. 5. The climate of X century allowed crossing the Alps: Luigi Mariani presents parallel evidences. 6. A list of 44 questions aswered by Paolo Rossi on modern physics/astrophysics is presented as a wish list of the level of culture of a secondary student. Three decades ago these topics were achievable only to University students: now are part of the public opinion, and a new framework has to be set by the teachers. 7. The dynamics of a micro-probe sent to alpha Centauri in 20 years is studied numerically. 8. The azimut of the Pyramid Cestia and 9. the height of the Vatican obelisk are studied exploiting solar ephemerides 10. The phases of pollen production of Cypress for 2016 are

As a result of this seismic interferometry experiment the 3D reflectivity model (frequencies and resolution ranges) was obtained. We proved also that the seismic interferometry approach can be applied in asynchronous seismic auscultation. The reflections detected in the virtual seismic sections are in agreement with the geological features encountered during the excavation of the tunnel and also with the petrophysical properties and parameters measured in previous geophysical borehole logging.

  2. Overview of balloon-borne aerosol measurements with the aerosol counter LOAC, with focus on the ChArMEx 2013 campaign

    NASA Astrophysics Data System (ADS)

    Dulac, François; Renard, Jean-Baptiste

    LOAC (Light Optical Aerosol Counter) is a new small optical particle counter/sizer of 250 grams designed to fly under all kinds of balloons. The measurements are conducted at two scattering angles: the first one, at 12°, is used to determine the aerosol particle concentrations in 19 size classes within a diameter range of 0.2-100 mm; the second angle, at 60°, is used to discriminate between different types of particles dominating different size classes. The sensor particularly discriminates wet or liquid particles, mineral dust, soot carbon particles and salts. Comparisons with measurements from other sensors at the surface are shown. We shall give a quick review of balloon-borne experiences since 2011 with LOAC under all kinds of balloons including tethered, sounding, open stratospheric, and new boundary-layer pressurized drifting balloons (BLBP) from CNES. Observation domains include the atmospheric surface layer, the boundary layer, the free troposphere and the lower stratosphere up to more than 35 km in altitude. Operations encompass a variety of environments including the Arctic (Reykjavik, Island, and Kiruna, Sweden), Brazil (Sao Paolo), the western Mediterranean Basin, southwestern France, peri-urban (Ile de France) and urban areas (Paris and Vienna). Results from the various campaigns will be illustrated including the study of fog events, urban aerosols, Saharan dust transport over France, stratospheric soot... Emphasis will be put on the ChArMEx campaign (the Chemistry-Aerosol Mediterranean Experiment) performed in summer 2013 in the Mediterranean basin: 19 LOAC flights have been performed under meteorological balloons and 12 under low altitude drifting balloons, most of them from Minorca Island (Spain) in June and early July and others from Levant Island (south of France) in late July and early August. Most of the flights were coupled with ozone concentration measurements (see presentation by F. Gheusi et al.). LOAC balloons were especially, but not

Combining economic loss from ten costliest flood events (from the same period) returns a loss (in the present value) exceeding 300bn USD. Locally, in Brazil, flood is the most damaging natural peril with alarming increase of events frequencies as 5 out of the 10 biggest flood losses ever recorded have occurred after 2009. The amount of economic and insured losses particularly caused by various flood types was the key driver of the local probabilistic flood model development. Considering the area of Brazil (being 5th biggest country in the World) and the scattered distribution of insured exposure, a domain covered by the model was limited to the entire state of Sao Paolo and 53 additional regions. The model quantifies losses on approx. 90 % of exposure (for regular property lines) of key insurers. Based on detailed exposure analysis, Impact Forecasting has developed this tool using long term local hydrological data series (Agencia Nacional de Aguas) from riverine gauge stations and digital elevation model (Instituto Brasileiro de Geografia e Estatística). To provide most accurate representation of local hydrological behaviour needed for the nature of probabilistic simulation, a hydrological data processing focused on frequency analyses of seasonal peak flows - done by fitting appropriate extreme value statistical distribution and stochastic event set generation consisting of synthetically derived flood events respecting realistic spatial and frequency patterns visible in entire period of hydrological observation. Data were tested for homogeneity, consistency and for any significant breakpoint occurrence in time series so the entire observation or only its subparts were used for further analysis. The realistic spatial patterns of stochastic events are reproduced through the innovative use of d-vine copula

    1.6% (7/450) of cases; binge drinking and other alcoholic games caused 23.3% (105/450) and 23.8% (107/450) of hospitalizations, respectively. On admission, 44.2% (199/450) of patients were assigned a red or yellow color code requiring immediate medical attention; about 14% of them required additional medical assistance (after being in the ED) or hospitalization, some in semi-intensive care units. Our study shows that the increased numbers of hospitalizations due to alcohol intoxication in the adolescent age group, as a consequence of NekNominate or other drinking games, is alarming and represents a serious public health issue. The potential markers of improper use of social networks must be clearly identified, including categories at risk of alcohol abuse, in order to develop intervention and prevention strategies in terms of education and awareness, which may help in averting potentially fatal episodes. ©Stefania Barbieri, Paolo Feltracco, Vittorio Lucchetta, Rosa Maria Gaudio, Alberto Tredese, Mauro Bergamini, Gianna Vettore, Vincenzo Pietrantonio, Francesco Maria Avato, Daniele Donato, Deris Gianni Boemo, Maria Vittoria Nesoti, Rossella Snenghi.

    Education and the National Program for the diffusion of Scientific Degrees (Progetto Lauree Scientifiche or PLS). In the last years has been mainly aimed to underline the connections between Astronomy, Astrophysics and the new materials involved in the astronomical techniques. The Sun has always been used in the course as a key element since the final product was the production of a self-constructed solar telescope able to be used to monitor the solar activity through Wolf's number estimation. In the third edition the project has been extended to other three Universities on the Italian territory: University of l'Aquila, University of Camerino and University of Calabria. Over the years more than 80 students and 50 teachers where directly involved and more than 50 different high schools on all the national territory, reaching thousands of their students in the final dissemination part of the program. 25 telescopes are currently in use in high school institutes all-over Italy. A book describing the project has been published by Springer in 2013 (STUDENTI-RICERCATORI per cinque giorni "Stage a Tor Vergata" Editors: Liù M.

Health and clinical outcomes were measured with both general indicators and disease-specific indicators and reported in 11/20 (55%) reviews. Patient-provider communication and patient satisfaction were the most investigated psychological and behavioral outcomes, reported in 13/20 (65%) and 12/20 (60%) reviews, respectively. Evaluation of health care utilization was included in 8/20 (40%) reviews, most of which focused on the economic effects on the health care system. Although observational studies and surveys have provided evidence of benefits and satisfaction for patients, there is still little reliable evidence from randomized controlled trials of improved health outcomes. Future evaluations of digital health interventions for citizens should focus on specific populations or chronic conditions which are more likely to achieve clinically meaningful benefits and use high-quality approaches such as randomized controlled trials. Implementation research methods should also be considered. We identified a wide range of effects and indicators, most of which focused on patients as main end users. Implications for providers and the health system should also be included in evaluations or monitoring of digital health interventions. ©Paolo Zanaboni, Patrice Ngangue, Gisele Irène Claudine Mbemba, Thomas Roger Schopf, Trine Strand Bergmo, Marie-Pierre Gagnon.

    Embryological development reflects evolutionary history. Understanding the processes of fetal growth is important for curing human birth defects and predicting damage to ecosystems from environmental insults. Tracing enzymatic and hormonal gradients during development, and correlating them to genetic cues dominate modern embryology. Previous work done tracing the mass transfer of elements has generally been limited to isotope spikes in vitro. Natural mass-dependent Ca and Sr isotopic ratios and radiogenic Sr isotopes have the potential to reveal both source and biochemical mechanism information about processes in vivo, but have not previously been extensively explored. The process when a hen lays a fertilized egg that becomes a chick includes formation and dissolution of calcium phosphate (bone) and calcium carbonate (shell). Skulan and DePaolo (1999) showed that chickens have 2% δ44/42Ca between a hen's bones and an egg white; this span represents more than 80% of the entire range of natural Ca isotope variation and illustrates there is significant variation to investigate. A striking feature of archosaurian development that also occurs in many mammals, including humans, is mass transfer of calcium from mother to embryo. The yolk of the domestic hen matures over 7-9 days, but the albumen, shell membranes and shell form in less than 20 hours. Domestic laying hens are at the physiological limit of egg production and selective breeding is no longer an effective method of increasing egg production. 60-75% of the shell's ~1.5 g of calcium comes from dietary sources, while 25-40% comes from the hen's medullary bone. Medullary bone is spicules formed in the marrow of long bones, and is a store of dietary calcium rapidly available for eggshell secretion. During in ovo development, the embryo's skeleton is formed from calcium in the yolk and by bulk dissolution of the eggshell's inner aspect via carbonic anhydrase in a process that has an effect on bone density similar to

We find that atmospheric sources (87Sr/86Srseawater = 0.709234; [2]) contribute about 13 % of Sr to the soil and are a minor but not negligible fraction in comparison to weathering supply from saprolite. Furthermore, the 87Sr/86Sr ratios determined for saprolite samples are in good agreement with the values reported for the local Illapel Plutonic Complex [3]. Hence, the top-soil atmospheric inputs are potentially influencing the plant's strategies of nutrient uplift, ultimately controlled by the plants' nutrient demand as a function of climate.

    NEW MAPPING OF RADITLADI BASIN AND DETAILED ANALYSIS OF ITS INNER PLAINS. Francesco Minelli 1, Carolina Giorgetti 1, Alessandro C.

Email: minelli91@yahoo.it. 2 CNR IRPI Perugia, 06123, Perugia. Introduction: The Raditladi basin is a large peak-ring impact crater discovered during the MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) first flyby of Mercury in January 2008 [1]. The Raditladi basin is relatively young [2], and the study of the internal structures give an indication of the processes that acted recently in Mercury's geological history. Geological mapping: We first present the geological mapping of Raditladi crater. In the map we defined different sub-units on the base of previous studies [4][5] and surface morphology and reflectance. Through a GIS software we associated a polygonal layer to each sub-unit, this allowed to distinguish nine different layers. Due to the similarities with the Rachmaninoff basin, to define sub-units mapped on Raditladi, we adopted Rachmaninoff crater's units definitions made by Marchi et al. (2011) [4]. Structures analysis : We also mapped secondary structures consisting in concentric troughs arranged in a circular pattern. We defined two different kinds of troughs: (i) structures characterized by a distinct flat floor and interpretable as grabens, and (ii) structures with linear and curvilinear segments [5]. Inner plain deposit: The analysis of the topography made possible the estimation of the deposit's thickness. The measurement of the thickness is possible thanks to the presence of two small craters, crater A and crater, located in Raditladi's Inner plain. Observing the morphology of the two small craters' rim and hummocky central floor, we distinguished two different units: the shallower consists in

  15. Long-lasting but Dim Brethren of Cosmic Flashes

    NASA Astrophysics Data System (ADS)

    2006-08-01

    astronomers with a large data set to document this new class of events. The group led by Elena Pian indeed confirmed that the event was tied to a supernova called SN 2006aj a few days later. Remarkable details about the chemical composition of the star debris continue to be analysed. The newly discovered supernova is dimmer than hypernovae associated with normal long gamma-ray bursts by about a factor of two, but it is still a factor of 2-3 more luminous than regular core-collapse supernovae. All together, these facts point to a substantial diversity between supernovae associated with GRBs and supernovae associated with X-ray flashes. This diversity may be related to the masses of the exploding stars. Whereas gamma-ray bursts probably mark the birth of a black hole, X-ray flashes appear to signal the type of star explosion that leaves behind a neutron star. Based on the VLT data, a team led by Paolo Mazzali of the Max Planck Institute for Astrophysics in Garching, Germany, postulate that the 18 February event might have led to a highly magnetic type of neutron star called a magnetar. Mazzali and his team find indeed that the star that exploded had an initial mass of 'only' 20 times the mass of the Sun. This is smaller, by about a factor two at least, than those estimated for the typical GRB-supernovae. "The properties of GRB 060218 suggest the existence of a population of events less luminous than 'classical' GRBs, but possibly much more numerous", said Mazzali. "Indeed, these events may be the most abundant form of X- or gamma-ray bursts in the Universe, but instrumental limits allow us to detect them only locally." The astronomers find that the number of such events could be about 100 times more numerous than typical gamma-ray bursts.

    The Nullarbor Region is a limestone desert in the south of Australia. It forms part of the larger Eucla Basin, which straddles the border between South Australia and Western Australia. The portion of the Eucla Basin lying in Westem Australia covers an area of about 104,000 km^2 (Bevan and Binns, 1989) and meteorites have been recovered from this region since 1971, new material being deposited at the Western Australia Museum. Between 21/3/92 and 6/4/92 a joint expedition between the Western Australia Museum and EUROMET recovered approximately 440 specimens of meteorites (total mass 13206 g) and 297 tektites. The expedition, whose members were Claude Perron (Paris), Christian Koeberl (Vienna), Georg Delisle (BGR Hannover), Gian- Paolo Sighinolfi (Modena), and Andrew Morse (OU) for Euromet, together with Wayne Smith (Australian Army) and Tom Smith (Perth Astronomical Observatory), was led by Dr Alex Bevan of the Western Australia Museum. Searching was carried out on foot with the participants spread out in a line with a 10-m spacing, walking along a compass bearing for approximately 10 km and back each day. Eight collecting regions were used, with a stop of about 2 days at each camp. Half of the searching was done near known strewn fields in order that the team become practised. Thus the expedition collected material at the following known sites. Camel Donga, Eucrite: The initial recovery was made in 1984 (Cleverly et al., 1986). The strewn field is about 8 km by 2-3 km at coordinates 30 degrees 19'S, 126 degrees 37'E. This expedition recovered 65 stones weighing a total of 2456 g, plus one stone of 4.8 g that was clearly chondritic in hand specimen. Mulga (north), H6: The initial recovery was made in 1964 (McCall, 1968). The strewn field is 8 km by 2 km at coordinates 30 degrees 11'S, 126 degrees 22'E and on this expedition 5 stones were recovered with a weight of 548 g. Also 110 stones (total mass 1535 g) that are certainly not H6 were found within a 100-m radius of

    LOAC (Light Optical Aerosol Counter) is a new small optical particle counter/sizer of ~250 grams designed to fly under all kinds of balloons. The measurements are conducted at two scattering angles (12° and 60°), allowing the determination of the aerosol particle concentrations in 19 size classes within a diameter range of ~0.2-100 µm and some identification of the nature of particles dominating different size classes. Following laboratory calibration, the sensor particularly discriminates wet or liquid particles, mineral dust, soot carbon particles and salts. Comparisons with other in situ sensors at the surface and with remote sensing measurements on the vertical were performed to give confidence in measurements. The instrument has been operated at the surface, under all kinds of balloons up to more than 35 km in altitude, including tethered, sounding, open stratospheric and new boundary-layer pressurized drifting balloons (BLPB) from CNES, and was tested on board a small UAV. Operations encompass a variety of environments including the Arctic (Reykjavik, Island, and Kiruna, Sweden), Brazil (Sao Paolo), the western Mediterranean Basin, southwestern France, peri-urban (Ile de France) and urban areas (Paris and Vienna). Presented results are focused on the LOAC balloon-borne measurements performed in the western Mediterranean basin during MISTRALS/ChArMEx campaigns (Mediterranean Integrated Studies aT Regional And Local Scales/the Chemistry-Aerosol Mediterranean Experiment; http://www.mistrals-hjome.org; http://charmex.lsce.ipsl.fr), with a focus on African dust events. Two test flights with a first version of LOAC under sounding balloons were first successfully performed in late June 2012 near Marseille during an intense dust event. In 2013, 19 LOAC flights have been performed under meteorological balloons and 12 under low altitude drifting balloons, most of them from Minorca Island (Spain) in June and early July and others from Levant Island (south of France

    < -5mm/yr) and seven of them with a potential to produce moderate damage (VSLOPE < -10mm/yr). One of the largest landslides in the range is the Bàlitx landslide (50 million m3 in volume), located on the steep coastal side (Mateos et al., 2013b). Within the landslide body, Roman cistern and old terrace walls have been identified. Numerous geomorphological features identified in its displaced mass (cracks, shallow slides and rockfalls) reveal that the landslide has not yet reached a state of equilibrium. Additionally, field observations determine that the northeastern sector of Bàlitx shows major activity signs. DInSAR results reveal that the rate of movement for the Bàlitx landslide is extremely low (- 5mm /yr on average) that could be interpreted as the residual displacement of the deep-seated rockslide. A major activity has also been detected in the northeastern sector of Bàlitx with the PSI technique, where velocities rates are slightly over -5 mm/yr. The outcomes of this work reveal the usefulness of landslide activity maps for environmental planning activities in cultural heritage sites.

    taking into account, not only the success, but also the mistakes. We have further validated the calibrated parameters along the Ma-road using the 63 rockfall recorded during the past 18 years along the road. 81.5% of the rockfalls are well represented by STONE modelling. Results have been exploited by the Road Maintenance Service of Mallorca for the design of the following road management plan: (1) Phase 1. Short-term. Design a specific plan for the road- sections where rockfalls were registered and modelling results were obtained. A large investment will be expended for implementation of retention and protection measures. (2) Phase 2. Medium-term. Design a specific plan for the road- sections where rockfalls were registered but no modelling results were obtained. For these cases, new studies at local scale are necessary as well as the application of other modelling software which include higher resolution input data. (3) Phase 3. Long-term. Design a specific plan for the road- sections where no rockfalls were registered but modelling results were obtained. These are potential rockfall areas and local and specific ground studies are necessaries. References Mateos RM (2006) Los movimientos de ladera en la Serra de Tramuntana (Mallorca).

    suggesting sequential failures, this object appeared as a good target to bring additional knowledge on the previously exposed issues. Our goal was to use TCN and to sample a maximum of individual lobes to be able to discuss: (i) the time of recurrence of successive extreme events, (ii) the respective roles of past climate variations versus earthquake forcing on the landslide trigger, and (iii) the impact of these mass remobilizations on local erosion rates compared to fluvial erosion rates and tectonic uplift rates (both known in this region). On average, three samples were extracted from individual meter-scale boulders sampled on seven different lobes of debris (~20 samples). Due to the lack of quartz in that volcanic lithology, 10Be was extracted from feldspaths for all samples. Half were additionally processed for 3He measurements on pyroxene, allowing to reduce the uncertainty on the derived exposure ages and to solve the production equation for both time and erosion variables. The obtained ages show a perfect consistency with the pattern of erosion, geomorphic surfaces and relative position of each lobes (i.e. younger from the toe to the top). These results highlight sequential failures staggered at the Pleistocene timescale, with some surprising time of recurrence ranging from 30 to 100 ka that may correspond to the main last climate variations in that region.

They also thank Richard Binzel, the General Editor of the Space Science Series, for his strong support and advice during this process, as well as the staff at the University of Arizona Press. Finally, editor Patrick Michel would like to thank his wife Delphine, who married him on June 14, 2013, almost at the birth of the book process. He is grateful that she was willing to put up with him as he spent many of his nights and weekends working on the book. Thanks to her support, their trajectories are as bounded as a perfectly stable asteroid binary system, and this was probably the best way to experience from the start what her life would be like with a researcher! Co-editor Bottke would also like to thank his wife Veronica and his children Kristina-Marie, Laura, and Julie, who make up his own favorite asteroid family. Since Asteroids III, the size distribution of the family members has been steadily changing, and who knows how many tiny new members it will contain by Asteroids V! Co-editor DeMeo would like to thank her husband Alfredo for his support and encouragement throughout the process of creating this book. They met at the beginning of her career in research, becoming an asteroid pair and now continuing on the same orbit in life.

    preliminary ARSs show some adaptation options allow recover up to ca. 2000 kg/ha. Compared to the historical yields recorded at Lleida province (2550 kg/ha in 1981-2010) our results indicate that adaptation is feasible and may help to reduce detrimental effects of CC. Our analysis evaluates if the explored adaptations fulfill the biophysical requirements to become a practical adaptive solution. This study exemplifies how adaptation options and their impacts can be analyzed, evaluated and communicated in a context of high regional uncertainty for current and future conditions and for short to long-term perspective.

A first clear example is the concentration of galaxies that appear uniformly yellow in PR Photo 06b/00 , apparently tracing a group of galaxies that was already assembled when the Universe was only 6 billion years old. A confirmation of the distance of a few of these galaxies has already been obtained by means of spectral observations in the framework of an ESO Large Programme , entitled "A Stringent Test on the Formation of Early Type and Massive Galaxies" and carried out by another group of astronomers [2]. A further clear example of a concentration of distant galaxies is seen in the upper right part of PR Photo 06b/00 . The very red colours of several galaxies in this sky area indicate that they are even more distant, "evolved" galaxies, already present when the Universe was only 1/3 of the current age.

  14. The Quiet Explosion

    NASA Astrophysics Data System (ADS)

    2008-07-01

    A European-led team of astronomers are providing hints that a recent supernova may not be as normal as initially thought. Instead, the star that exploded is now understood to have collapsed into a black hole, producing a weak jet, typical of much more violent events, the so-called gamma-ray bursts. The object, SN 2008D, is thus probably among the weakest explosions that produce very fast moving jets. This discovery represents a crucial milestone in the understanding of the most violent phenomena observed in the Universe. Black Hole ESO PR Photo 23a/08 A Galaxy and two Supernovae These striking results, partly based on observations with ESO's Very Large Telescope, will appear tomorrow in Science Express, the online version of Science. Stars that were at birth more massive than about 8 times the mass of our Sun end their relatively short life in a cosmic, cataclysmic firework lighting up the Universe. The outcome is the formation of the densest objects that exist, neutron stars and black holes. When exploding, some of the most massive stars emit a short cry of agony, in the form of a burst of very energetic light, X- or gamma-rays. In the early afternoon (in Europe) of 9 January 2008, the NASA/STFC/ASI Swift telescope discovered serendipitously a 5-minute long burst of X-rays coming from within the spiral galaxy NGC 2770, located 90 million light-years away towards the Lynx constellation. The Swift satellite was studying a supernova that had exploded the previous year in the same galaxy, but the burst of X-rays came from another location, and was soon shown to arise from a different supernova, named SN 2008D. Researchers at the Italian National Institute for Astrophysics (INAF), the Max-Planck Institute for Astrophysics (MPA), ESO, and at various other institutions have observed the supernova at great length. The team is led by Paolo Mazzali of INAF's Padova Observatory and MPA. "What made this event very interesting," says Mazzali, "is that the X-ray signal was very

  17. Evidence for Ultra-Energetic Particles in Jet from Black Hole

    2006-06-01

    shoot out from the black hole at close to the speed of light and then release their energy as radiation as far out as they are seen, the particles have to be accelerated locally, where they produce their emission. Both teams also used data from the third of NASA's Great Observatories, the Hubble Space Telescope, and the radio telescopes of the Very Large Array (VLA). The three space telescopes and the VLA "see" emission of different wavelengths from celestial objects, and the combined data was essential to reveal the new comprehensive perspective on the jets. "The new observations show that the flow structure of this jet is more complicated than had been assumed previously," Jester explains. "That the present evidence favors the synchrotron model deepens the mystery of how jets produce the ultra-energetic particles that radiate at X-ray wavelengths." "Our results call for a radical rethink of the physics of relativistic jets that black holes drive," said Uchiyama. "But, we now have a crucial new clue to solving one of the major mysteries in high-energy astrophysics." Other authors on the papers include Jeffrey Van Duyne and Paolo Coppi at Yale; C.C. Cheung at Stanford University; Rita Sambruna at NASA/GSFC, Greenbelt, MD; Tadayuki Takahashi at ISAS/JAXA, Japan; Laura Maraschi and Fabrizio Tavecchio at the Osservatorio Astronomico di Brera, Milan; Dan Harris from the SAO; Herman Marshall at MIT; and Klaus Meisenheimer at Max Planck Institute for Astronomy in Heidelberg.

    Enhanced recovery after surgery (ERAS®) is a strategy that seeks to reduce patients’ perioperative stress response, thereby reducing potential complications, decreasing hospital length of stay and enabling patients to return more quickly to their baseline functional status. The concept was introduced in the late 1990s and was first adopted in patients undergoing open colorectal surgery. Since then, the concept of ERAS has been adopted by multiple surgical specialties. The diffusion of video-assisted thoracic surgery lobectomy (VATS-L) sets also the surgical treatment of lung cancer as a new area for ERAS development. In this paper, we present the Italian VATS Group (www.vatsgroup.org) surgical protocol as part of the ERAS clinical pathway belonging to the VATS-L national database. PMID:29629203

    present time. More information The results described in this Press Release are presented in a research paper "The Lyman-alpha forest of a Lyman-Break Galaxy: VLT Spectra of MS 1512-cB58 at z = 2.724" by Sandra Savaglio, Nino Panagia and Paolo Padovani, appearing in the research journal "Astrophysical Journal" this month. Notes [1]: The team consists of Sandra Savaglio (Johns Hopkins University, Baltimore, MD, USA, and Rome Observatory, Italy), Nino Panagia and Paolo Padovani (both European Space Agency and Space Telescope Science Institute, Baltimore) [2]: The measured redshift of MS 1512-cB58 is z = 2.724. In astronomy, the redshift denotes the fraction by which the lines in the spectrum of an object are shifted towards longer wavelengths. The observed redshift of a distant cloud or galaxy gives a direct estimate of the apparent recession velocity as caused by the universal expansion. Since the expansion rate increases with distance, the velocity is itself a function (the Hubble relation) of the distance to the object. The distances indicated in the text are based on an age of the Universe of 15 billion years. At the indicated redshift, the Lyman-alpha line of atomic hydrogen (rest wavelength 121.6 nm) is observed at 452.8 nm, i.e. in the blue spectral region. The Lyman-alpha absorption lines from intergalactic clouds along the line-of-sight (and at lower redshifts) are observed at shorter wavelengths. The lower limit of the UVES spectrum of MS 1512-cB58 (415 nm) corresponds to a Lyman-alpha redshift of 2.41, i.e. a distance of about 7.5 billion light-years. [3]: The importance of the Lyman-alpha line in absorption is that it is exquisitely sensitive to the presence of neutral hydrogen which only constitutes a small fraction of the total amount of hydrogen in the intergalactic medium (about 1/10,000). Still, the observed Ly-alpha forest is extremely rich. What we see is most likely the "tip of the iceberg" only and hydrogen in the intergalactic medium at high redshift is

    objects? Since only a few have been identified so far, any statistics must be quite uncertain. Until now, the best estimates have been of the order of 1 per 3,500 cubic light-years (0.01/pc 3 ). A surprising aspect of this discovery is that NTTDF J1205-0744 was found within a sky area of only 2.3 x 2.3 arcmin 2 , specially selected to be as "empty" as possible in order to facilitate studies of distant galaxies. Based on the above density estimate, the chance of finding such an object should only have been about 1%. Based on model predictions, the chance would have been even smaller than this. Searches like the one described here, based on the combination of optical and infrared data, therefore appear particularly effective at detecting such objects. It is now of high interest to test if this first discovery was just extremely lucky, or if the space density of these extreme objects is in fact much higher than expected. More information A research article about these new results ( Discovery of a faint Field Methane Brown Dwarf from ES0 NTT and VLT observations), will appear in the European journal Astronomy & Astrophysics . Note [1] The team consists of Jean Gabriel Cuby, Alan Moorwood, Sandro D'Odorico, Chris Lidman, Fernando Comeron, Jason Spyromilio (ESO) and Paolo Saracco (Osservatorio Astronomico di Brera, Merate, Milan, Italy). [2] A more nearby, hotter brown dwarf, KELU-1 , was found at La Silla in 1997 at a distance of 33 light-years, cf. ESO Press Release 07/97.

[3]: While it is apparent that some mass is transferred from the Planetary Nebulae to the stars, the details of this process are not clear. It may have happened before the stars here observed were formed, or later. In the latter case, the accretion may have occurred only during a particular evolutionary phase, some 100 million years after the cluster formed, i.e. about 11 to 15 billion years ago, and in very dense environments. Moreover, the accretion rate will depend on the relative velocities: only stars that move slowly with respect to the interstellar medium has a good chance of accreting matter. This may also be (part of) an explanation of the observed, large differences from star to star.

    representative of this elusive class of objects (referred to as ' Type II Quasars ') which are believed to account for approximately 90% of the black-hole-powered quasars in the distant Universe. The 'sum' of the identified Chandra X-ray sources in the CDFS was found to match both the intensity and the spectral properties of the observed X-ray background. This important result is a significant step forward towards the definitive resolution of this long-standing cosmological problem. Naturally, ESO astronomer Piero Rosati and his colleagues are thrilled: " It is clearly the combination of the new and detailed Chandra X-ray observations and the enormous light-gathering power of the VLT that has been instrumental to this success. " However, he says, " the identification of the remaining Chandra X-ray sources will be the next challenge for the VLT since they are extremely faint. This is because they are either heavily obscured by dust or because they are extremely distant ". More Information This Press Release is issued simultaneously with a NASA Press Release (see also the Harvard site ). Some of the first results are described in a research paper ("First Results from the X-ray and Optical Survey of the Chandra Deep Field South" available on the web at astro-ph/0007240. More information about science results from the Chandra X-Ray Observatory may be found at: http://asc.harvard.edu/. The optical survey of CDFS at ESO with the Wide-Field Imager is described in connection with PR Photos 46a-b/99 ('100,000 galaxies at a glance').

    Amazonia/Yungas are better protected, in terms of biodiversity and environmental damage, than other conservation units such as national or regional reserves [23, 24]. Yet deforestation, resource extraction and climate change threaten all parts of the Amazonia/Yungas [19, 25-28], and indigenous communities, amongst the most marginalized peoples in Latin America [29], are experiencing increasing threats to their territories, and their health and well-being [20]. Figures 1-3 show different aspects of the Andean Yungas and high mountain ecosystems of Argentina. The ecosystems are highly biodiverse. We are only beginning to understand the extent of their importance for human well-being, and these incredible forests are at risk from deforestation, mining and climate change. Figure 1 Figure 1. Rio Cochuna in Tucumán, Argentina, part of the vital and extensive river system of the Andean Yungas, home to amazing and underexplored biodiversity. By Carolyn Stephens. Figure 2 Figure 2. Argiope argentata—widespread and striking, this spider can eat twice her weight in insects and her venom is thought to have medicinal properties. By Carolyn Stephens. Figure 3 Figure 3. Humming birds may not seem to have a direct ecosystem service, but they, along with many insect species, are important pollinators of plants and trees which themselves may be directly important for human health. By Alfredo Gutierrez. It is notable that, recognizing their vital role in ecosystem understanding protection, indigenous peoples and local communities now play an important part in global policy processes, including the United Nations Convention on Biological Diversity (CBD) and the UN Framework Convention on Climate Change (UNFCCC) [30]. In 2011, the IUCN met with indigenous representatives and conservation organizations to discuss conservation priorities in the context of indigenous rights. IUCN agreed to review the implementation of resolutions related to indigenous peoples taken at the 4th World

    , for the immediate future, the accuracy of this age determination does not really depend on the VLT spectrum. For the time being, the real problems are the present uncertainties in the available laboratory data for uranium by means of which the measured line strengths are converted into element abundances. In addition, the nuclear-physics calculations of the initial isotope production ratios introduce errors that are larger than those of the spectral observation. Thus, improved measurements of those physical data are necessary in order to read more accurately the cosmic clock in CS 31082-001 from the existing observational data. The relevant laboratory measurements are now underway at the CEA, Saclay, France, and the University of Lund, Sweden. In the meantime, the team is trying to find other stars like CS 31082-001 . There may not be many, but if the uranium line can be seen and measured in more spectra, it will also become possible to judge whether those very old stars, as surmised, are all of about the same age, i.e. that of our Milky Way galaxy. More information The research described in this Press Release is reported in a research article ("Measurement of stellar age from uranium decay"), that appears in the international research journal Nature on Thursday, February 8, 2001.

    through an exhaustive chronological account of the major milestones. It is clear that the concept of excluded volume as a key factor remains central to the concept of molecular crowding. As a consequence, simple descriptive paradigms borrowed essentially from colloid physics may still provide useful tools to understand the subtle effects of crowding and confinement in living matter. The contiguity between crowding, colloids and soft matter further emerged as an important concept in the course of the conference in several theoretical lectures and a few experimental ones. Dave Thirumalai, from the University of Maryland (USA), one of the most active theoreticians in the field of theoretical biophysics, outlined scaling theories, concepts from colloid literature and different simulation techniques to describe scenarios for crowding-induced changes in the structure and dynamics of proteins and RNA. In particular, he showed the importance of the shape of crowding particles in affecting folding oligomerization of amyloidogenic peptides. Johannes Schöneberg, from IMPRS, Mathematics Institute (Germany), illustrated ReaDDy , a newly developed particle-based simulation software tool for reaction-diffusion dynamics, developed in the group of Frank Noe at EMPRS. He showed that ReaDDy makes it possible to bridge the gap between soft matter and molecular dynamics (MD) simulations on the one hand and particle-based stochastic reaction-diffusion simulations on the other. We asked Johannes to organize a tutorial session to lead interested participants into the package and 'get their hands wet' under the guidance of the developers. The tutorial session was indeed successful and the broad possibilities offered by the simulation toolkit appeared to be clear to the participants. Paolo De Los Rios, from the Ecole Polytechnique Fédérale de Lausanne (EPFL, Switzerland), examined the complexity of the effects caused by crowding conditions from the point of view of statistical physics.

    somewhat similar to the Earth, but it is too cold for life as we know it, and because of its comparatively small size, the atmospheric pressure is very low. It would in principle be possible to detect the outermost planet with the HST, if the distance to this planetary system was less than about 30 light-years. Ireland: Mr. Declan MacCuarta (Teacher), Mr. Colm McLoughlin (St. Peter's College, Wexford, Co. Wexford) The nearest star, Alpha Centauri, is a double star and a hypothetical planetary system around the A-component, a solar-type star, is studied in some detail. The presence of the companion star makes some planetary orbits unstable. In this project, 4 planets are placed within 2 AU (300 million km) of the central star; 3 of these are terrestrial (no. 3 is Earth-like) and the outermost is a small gaseous planet. Cometary orbits may be very complex in this gravitatinal field. A planetary system like the one described may be barely observable with the Hubble Space Telescope, and only if one of the planets passes in front of the star (an `occultation') and its light diminishes accordingly. Italy: Mr. Pasquale Ciarletta, Ms. Francesca D'elia, Ms. Ada Fortugna (Teacher), Mr. Alfredo Pudano (Liceo Scientifico `Leonardo da Vinci', Reggio Calabria) This group built a spectrograph from scratch, with a grating and all the usual optical parts. They were able to calibrate the solar spectrum with the help of standard lamps and in this way, they observed several prominent, solar absorption lines. Among them were the H-alpha line at 6562 A, the sodium D-lines at 5890--96 And the magnesium triplet near 5175 A. These observations were made with the eye and also with the photographic recording technique. They were planning to observe the spectra of some stars also, but in the end time was too short and they had to hurry to send in the report. The Netherlands: Mr. Alex De Beer, Mr. KlAs Huijbregts, Mr. Ruud Nellen (Norbertuscollege, RosendAl) This team has designed their own planetary
